Amaury Forgeot d'Arc8530e852008-09-09 07:28:22 +000095 the "-c" and "-m" parameters. Now the behaviour is as expected under Linux,
96 although under Windows it fails at a later point.
Antoine Pitrou5651eaa2008-09-06 20:46:58 +000097
Benjamin Peterson791dc2f2008-09-05 23:27:15 +000098- Issue #3279: Importing site at interpreter was failing silently because the
99 site module uses the open builtin which was not initialized at the time.
100
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +0000101- Issue #3660: Corrected a reference leak in str.encode() when the encoder

Brett Cannon8a9583e2008-09-04 05:04:25 +0000108 tokenized by either a file path or file pointer for the benefit of
109 PyTokenizer_FindEncoding().
110
Antoine Pitroufff95302008-09-03 18:58:51 +0000111- Issue #3696: Error parsing arguments on OpenBSD <= 4.4 and Cygwin. On
112 these systems, the mbstowcs() function is slightly buggy and must be
113 replaced with strlen() for the purpose of counting of number of wide
114 characters needed to represent the multi-byte character string.
115
Antoine Pitrou658fad82008-09-03 18:34:34 +0000116- Issue #3697: "Fatal Python error: Cannot recover from stack overflow"

128 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
129 was correctly parsed but parsing of subsequent arguments failed.
130
Amaury Forgeot d'Arcdb26f7c2008-08-29 07:13:32 +0000131- Issue #3611: An exception __context__ could be cleared in a complex pattern

135 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
136 mechanism. In the process, fix a bug where isinstance() and issubclass(),
137 when given a tuple of classes as second argument, were looking up
138 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
139 type object.
140

195
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000196- The bsddb module (and therefore the dbm.bsd module) has been removed.
Gregory P. Smith451e99b2008-09-04 04:46:48 +0000197 It is now maintained outside of the standard library at
198 http://www.jcea.es/programacion/pybsddb.htm.
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000199

228 Python 2.6 one, since the intention is to keep an unified 2.x/3.x codebase.
229 The Python code is automatically translated using "2to3". Please, do not
230 update this code in Python 3.0 by hand. Update the 2.6 one and then
231 do "2to3".
232
Benjamin Peterson791dc2f2008-09-05 23:27:15 +0000233- The _bytesio and _stringio modules are now compiled into the python binary.

Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000262Core and Builtins
263-----------------
264
Benjamin Petersonbc74e5b2008-08-23 20:19:17 +0000265- Issue #3653: Fix a segfault when sys.excepthook was called with invalid
266 arguments.
267
Antoine Pitrou616d2852008-08-19 22:09:34 +0000268- Issue #2394: implement more of the memoryview API, with the caveat that
269 only one-dimensional contiguous buffers are supported and exercised right
270 now. Slicing, slice assignment and comparison (equality and inequality)
271 have been added. Also, the tolist() method has been implemented, but only
272 for byte buffers. Endly, the API has been updated to return bytes objects
273 wherever it used to return bytearrays.
274
Antoine Pitrouee58fa42008-08-19 18:22:14 +0000275- Issue #3560: clean up the new C PyMemoryView API so that naming is
276 internally consistent; add macros PyMemoryView_GET_BASE() and
277 PyMemoryView_GET_BUFFER() to access useful properties of a memory views
278 without relying on a particular implementation; remove the ill-named
279 PyMemoryView() function (PyMemoryView_GET_BUFFER() can be used instead).
280
Thomas Hellerf5049fc2008-08-19 19:49:49 +0000281- ctypes function pointers that are COM methods have a boolean True
282 value again.
283
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000284- Issue #1819: function calls with several named parameters are now on
285 average 35% faster (as measured by pybench).
286
Marc-André Lemburg4cc0f242008-08-07 18:54:33 +0000287- The undocumented C APIs PyUnicode_AsString() and
288 PyUnicode_AsStringAndSize() were made private to the interpreter, in
289 order to be able to refine their interfaces for Python 3.1.
290
291 If you need to access the UTF-8 representation of a Unicode object
292 as bytes string, please use PyUnicode_AsUTF8String() instead.
293
Antoine Pitrouaf14b792008-08-07 21:50:41 +0000294- Issue #3460: PyUnicode_Join() implementation is 10% to 80% faster thanks
295 to Python 3.0's stricter semantics which allow to avoid successive
296 reallocations of the result string (this also affects str.join()).

300-------
301
Hye-Shik Chang50d1f792008-08-23 08:03:03 +0000302- Issue #1276: Added temporary aliases for CJK Mac encodings to resolve
303 a build problem on MacOS with CJK locales. It adds four temporary
304 mappings to existing legacy codecs that are virtually compatible
305 with Mac encodings. They will be replaced by codecs correctly
306 implemented in 3.1.
307
Amaury Forgeot d'Arc41e36672008-08-20 21:35:50 +0000308- Issue #3614: Corrected a typo in xmlrpc.client, leading to a NameError
309 "global name 'header' is not defined".
310
Antoine Pitroufd036452008-08-19 17:56:33 +0000311- Issue #2834: update the regular expression library to match the unicode
312 standards of py3k. In other words, mixing bytes and unicode strings
313 (be it as pattern, search string or replacement string) raises a TypeError.
314 Moreover, the re.UNICODE flag is enabled automatically for unicode patterns,
315 and can be disabled by specifying a new re.ASCII flag; as for bytes
316 patterns, ASCII matching is the only option and trying to specify re.UNICODE
317 for such patterns raises a ValueError.
318
Guido van Rossum52dbbb92008-08-18 21:44:30 +0000319- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
320 Code contributed by Matt Giuca. quote() now encodes the input
321 before quoting, unquote() decodes after unquoting. There are
322 new arguments to change the encoding and errors settings.
323 There are also new APIs to skip the encode/decode steps.

327 based hash because that hash mechanism is not correct for numeric types.

349 file name rather than a ZipInfo instance, so files are extracted with
350 mode 0600 rather than 000 under Unix.

Guido van Rossumf4169812008-03-17 22:56:06 +0000720- A new pickle protocol (protocol 3) is added with explicit support
721 for bytes. This is the default protocol. It intentionally cannot
722 be unpickled by Python 2.x.
723
724- When a pickle written by Python 2.x contains an (8-bit) str
725 instance, this is now decoded to a (Unicode) str instance. The
726 encoding used to do this defaults to ASCII, but can be overridden
727 via two new keyword arguments to the Unpickler class. Previously
728 this would create bytes instances, which is usually wrong: str
729 instances are often used to pickle attribute names etc., and text is
730 more common than binary data anyway.
731
Martin v. Löwis071ef772008-03-08 11:24:24 +0000732- Default to ASCII as the locale.getpreferredencoding, if the POSIX

740 has been renamed tokenize and now works with bytes rather than
741 strings. A new detect_encoding function has been added for
742 determining source file encoding according to PEP-0263. Token
743 sequences returned by tokenize always start with an ENCODING token
744 which specifies the encoding used to decode the file. This token is
745 used to encode the output of untokenize back to bytes.

Guido van Rossume239b002008-01-06 00:44:20 +0000893C API
894-----
895
896- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
897 Py_TYPE and Py_REFCNT.
898
Georg Brandl52b92cc2008-05-25 09:43:03 +0000899- New API PyImport_ImportModuleNoBlock(), works like
900 PyImport_ImportModule() but won't block on the import lock
901 (returning an error instead).

Fred Drake0e474a82007-10-11 18:01:43 +0000904What's New in Python 3.0a2?
Christian Heimesbc873412007-12-08 22:11:32 +0000905===========================
Fred Drake0e474a82007-10-11 18:01:43 +0000906
Guido van Rossum99533a92007-12-06 05:07:41 +0000907*Release date: 07-Dec-2007*
908
909(Note: this list is incomplete.)
Fred Drake0e474a82007-10-11 18:01:43 +0000910
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000911Core and Builtins
912-----------------
913
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000914- str8 now has the same construction signature as bytes.
915
Georg Brandl52b92cc2008-05-25 09:43:03 +0000916- Comparisons between str and str8 now return False/True for ==/!=.
917 sqlite3 returns str8 when recreating on object from it's __conform__
918 value. The struct module returns str8 for all string-related
919 formats. This was true before this change, but becomes more
920 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000921
Georg Brandl52b92cc2008-05-25 09:43:03 +0000922- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
923 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000924
925- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
926
927- Changed `__file__` and `co_filename` to unicode. The path names are decoded
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000928 with `Py_FileSystemDefaultEncoding` and a new API method
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000929 `PyUnicode_DecodeFSDefault(char*)` was added.
930
Georg Brandl52b92cc2008-05-25 09:43:03 +0000931- io.open() and _fileio.FileIO have grown a new argument closefd. A
932 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000933
Georg Brandl52b92cc2008-05-25 09:43:03 +0000934- Added a new option -b to issues warnings (-bb for errors) about
935 certain operations between bytes/buffer and str like str(b'') and
936 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000937
Georg Brandl52b92cc2008-05-25 09:43:03 +0000938- The standards streams sys.stdin, stdout and stderr may be None when
939 the when the C runtime library returns an invalid file descriptor
940 for the streams (fileno(stdin) < 0). For now this happens only for
941 Windows GUI apps and scripts started with `pythonw.exe`.
Christian Heimes58cb1b82007-11-13 02:19:40 +0000942
Christian Heimesbce52be2007-11-17 19:08:41 +0000943- Added PCbuild9 directory for VS 2008.
944
Georg Brandl52b92cc2008-05-25 09:43:03 +0000945- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
946 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000947
Georg Brandl52b92cc2008-05-25 09:43:03 +0000948- Unbound methods are gone for good. ClassObject.method returns an
949 ordinary function object, instance.method still returns a bound
950 method object. The API of bound methods is cleaned up, too. The
951 im_class attribute is removed and im_func + im_self are renamed to
952 __func__ and __self__. The factory PyMethod_New takes only func and
953 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000954
Georg Brandl52b92cc2008-05-25 09:43:03 +0000955- intobject.h is no longer included by Python.h. The remains were
956 moved to longobject.h. It still exists to define several aliases
957 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000958
Christian Heimesa37d4c62007-12-04 23:02:19 +0000959- Removed sys.maxint, use sys.maxsize instead.
960
Fred Drake0e474a82007-10-11 18:01:43 +0000961Extension Modules
962-----------------
963
964- The `hotshot` profiler has been removed; use `cProfile` instead.
965
Brett Cannone9fd2312007-10-12 19:18:19 +0000966Library
967-------
968
Georg Brandl52b92cc2008-05-25 09:43:03 +0000969- When loading an external file using testfile(), the passed-in
970 encoding argument was being ignored if __loader__ is defined and
971 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000972
Georg Brandl52b92cc2008-05-25 09:43:03 +0000973- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
974 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000975
Christian Heimesc9543e42007-11-28 08:28:28 +0000976- Removed the 'new' module.
977
Georg Brandl52b92cc2008-05-25 09:43:03 +0000978- Removed all types from the 'types' module that are easily accessable
979 through builtins.
Brett Cannone9fd2312007-10-12 19:18:19 +0000980
Georg Brandl52d168a2008-01-07 18:10:24 +0000981
Guido van Rossum4405cf32007-08-30 17:16:55 +0000982What's New in Python 3.0a1?
Guido van Rossum45aecf42006-03-15 04:58:47 +0000983==========================
Thomas Wouters4d70c3d2006-06-08 14:42:34 +0000984
Guido van Rossum4405cf32007-08-30 17:16:55 +0000985*Release date: 31-Aug-2007*
Neal Norwitz4886cc32006-08-21 17:06:07 +0000986
987Core and Builtins
988-----------------
989
Martin v. Löwis47383402007-08-15 07:32:56 +0000990- PEP 3131: Support non-ASCII identifiers.
991
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000992- PEP 3120: Change default encoding to UTF-8.
993
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000994- PEP 3123: Use proper C inheritance for PyObject.
995
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000996- Removed the __oct__ and __hex__ special methods and added a bin()
997 builtin function.
998
Georg Brandl52b92cc2008-05-25 09:43:03 +0000999- PEP 3127: octal literals now start with "0o". Old-style octal
1000 literals are invalid. There are binary literals with a prefix of
1001 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +00001002
Guido van Rossume7ba4952007-06-06 23:52:48 +00001003- None, True, False are now keywords.
1004
Guido van Rossum29478ef2007-05-29 00:39:44 +00001005- PEP 3119: isinstance() and issubclass() can be overridden.
1006
Guido van Rossumebe3e162007-05-17 18:20:34 +00001007- Remove BaseException.message.
1008
Guido van Rossum1bc535d2007-05-15 18:46:22 +00001009- Remove tuple parameter unpacking (PEP 3113).
1010
Georg Brandl52b92cc2008-05-25 09:43:03 +00001011- Remove the f_restricted attribute from frames. This naturally leads
1012 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +00001013
Georg Brandl52b92cc2008-05-25 09:43:03 +00001014- PEP 3132 was accepted. That means that you can do ``a, *b =
1015 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +00001016
Georg Brandl52b92cc2008-05-25 09:43:03 +00001017- range() now returns an iterator rather than a list. Floats are not
1018 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +00001019
Nick Coghlan650f0d02007-04-15 12:05:43 +00001020- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +00001021 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +00001022
Guido van Rossume27dc722007-03-27 22:37:34 +00001023- By default, != returns the opposite of ==, unless the latter returns
1024 NotImplemented.
1025
Georg Brandl52b92cc2008-05-25 09:43:03 +00001026- Patch #1680961: sys.exitfunc has been removed and replaced with a
1027 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +00001028
Georg Brandl801dd732007-03-18 20:18:31 +00001029- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +00001030 keyword arg in the class statement, which can now use the full
1031 syntax of a parameter list. Also, the metaclass can implement a
1032 __prepare__ function which will be called to create the dictionary
1033 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +00001034
Georg Brandl428f0642007-03-18 18:35:15 +00001035- The long-deprecated argument "pend" of PyFloat_FromString() has been
1036 removed.
1037
Georg Brandle32b4222007-03-10 22:13:27 +00001038- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +00001039 its argument, if it exists. If not, it will work like before. This
1040 allows customizing the output of dir() in the presence of a
1041 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +00001042
Neal Norwitz8dfc4a92007-08-11 06:39:53 +00001043- Removed support for __members__ and __methods__.
1044
Georg Brandle32b4222007-03-10 22:13:27 +00001045- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +00001046
Georg Brandle32b4222007-03-10 22:13:27 +00001047- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001048 functionality formerly known as raw_input(); the name raw_input() is
1049 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +00001050
Georg Brandl52b92cc2008-05-25 09:43:03 +00001051- Classes listed in an 'except' clause must inherit from
1052 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +00001053
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001054- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +00001055 and .keys(), .items(), .values() return dict views, which behave
1056 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001057
Guido van Rossum8b545362007-02-09 23:52:14 +00001058- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001059 'softspace' attribute of files is now gone (since print() doesn't
1060 use it). A side effect of this change is that you can get
1061 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +00001062
1063 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +00001064 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +00001065
1066 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +00001067
Brett Cannon398db8b2007-01-29 23:44:37 +00001068- PEP 3102: keyword-only arguments.
1069
Georg Brandl52b92cc2008-05-25 09:43:03 +00001070- Int/Long unification is complete. The 'long' built-in type and
1071 literals with trailing 'L' or 'l' have been removed. Performance
1072 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +00001073
1074- 'except E, V' must now be spelled as 'except E as V' and deletes V
1075 at the end of the except clause; V must be a simple name.
1076
Neal Norwitzc1505362006-12-28 06:47:50 +00001077- Added function annotations per PEP 3107.
1078
Georg Brandl52b92cc2008-05-25 09:43:03 +00001079- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +00001080
1081 >>> def f(x):
1082 ... def inc():
1083 ... nonlocal x
1084 ... x += 1
1085 ... return x
1086 ... return inc
1087 ...
1088 >>> inc = f(0)
1089 >>> inc()
1090 1
1091 >>> inc()
1092 2
1093
Georg Brandl66a796e2006-12-19 20:50:34 +00001094- Moved intern() to sys.intern().
1095
1096- exec is now a function.
1097
1098- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +00001099
Neal Norwitz4886cc32006-08-21 17:06:07 +00001100- Classic classes are a thing of the past. All classes are new style.
1101
1102- Exceptions *must* derive from BaseException.
1103
1104- Integer division always returns a float. The -Q option is no more.
1105 All the following are gone:
1106 * PyNumber_Divide and PyNumber_InPlaceDivide
1107 * __div__, __rdiv__, and __idiv__
1108 * nb_divide, nb_inplace_divide
1109 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
1110 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
1111 if we want to re-use __div__ and friends. If we do, it will make
1112 it harder to write code for both 2.x and 3.x.)
1113
1114- 'as' and 'with' are keywords.
1115
1116- Absolute import is the default behavior for 'import foo' etc.
1117
Georg Brandl52b92cc2008-05-25 09:43:03 +00001118- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001119
Georg Brandl52b92cc2008-05-25 09:43:03 +00001120- Removed these Python builtins: apply(), callable(), coerce(),
1121 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +00001122
Georg Brandl52b92cc2008-05-25 09:43:03 +00001123- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001124
Georg Brandl52b92cc2008-05-25 09:43:03 +00001125- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001126
1127- Remove C API support for restricted execution.
1128
Guido van Rossumcf1be882007-08-30 22:07:17 +00001129- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +00001130 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +00001131 sequences of unequal length -- it now stops after the shortest one
1132 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001133
Georg Brandl52b92cc2008-05-25 09:43:03 +00001134- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001135
1136- Added class decorators per PEP 3129.
1137

1139Extension Modules
1140-----------------
1141
Georg Brandl52b92cc2008-05-25 09:43:03 +00001142- Removed the imageop module. Obsolete long with its unit tests
1143 becoming useless from the removal of rgbimg and imgfile.
Neal Norwitz4886cc32006-08-21 17:06:07 +00001144
Georg Brandl52b92cc2008-05-25 09:43:03 +00001145- Removed these attributes from the operator module: div, idiv,
1146 __div__, __idiv__, isCallable, sequenceIncludes.
1147
1148- Removed these attributes from the sys module: exc_clear(), exc_type,
1149 exc_value, exc_traceback.

1152Library
1153-------
1154
Georg Brandl52b92cc2008-05-25 09:43:03 +00001155- Removed the compiler package. Use of the _ast module and (an
1156 eventual) AST -> bytecode mechanism.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001157
Georg Brandl52b92cc2008-05-25 09:43:03 +00001158- Removed these modules: audiodev, Bastion, bsddb185, exceptions,
1159 linuxaudiodev, md5, MimeWriter, mimify, popen2, rexec, sets, sha,
1160 stringold, strop, sunaudiodev, timing, xmllib.
Guido van Rossum33d26892007-08-05 15:29:28 +00001161
Georg Brandl52b92cc2008-05-25 09:43:03 +00001162- Moved the toaiff module to Tools/Demos.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001163
