12TO DO
13-----
14
Georg Brandl66a796e2006-12-19 20:50:34 +0000[diff] [blame]15- See PEP 3000, 3100.
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]16
17- Test merging certain changes from the 2.5 HEAD code.
18
19- Weed really old/weird stuff from the library.
20
21- Unify range() and xrange().
22
23- Revamp the dict API: keys(), values(), items() return iterators, etc.
24
25- Add the bytes type.
26
27- Rework the standard I/O library to use bytes for binary files.
28
29- Make strings all Unicode.
30
31- Get rid of classic class implementation.
32
33- Get rid of various compatibility-related flags (e.g. division flags).

Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]36Core and Builtins
37-----------------
38
Guido van Rossumab186842007-01-14 03:42:30 +0000[diff] [blame^]39- Int/Long unification is halfway complete. There are a few broken tests,
40 the 'long' built-in hasn't been removed yet, and literals with trailing
41 'L' or 'l' are still recognized. Performance may be sub-optimal.
42
43- 'except E, V' must now be spelled as 'except E as V' and deletes V
44 at the end of the except clause; V must be a simple name.
45
Neal Norwitzc1505362006-12-28 06:47:50 +0000[diff] [blame]46- Added function annotations per PEP 3107.
47
Georg Brandl66a796e2006-12-19 20:50:34 +0000[diff] [blame]48- Moved intern() to sys.intern().
49
50- exec is now a function.
51
52- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +0000[diff] [blame]53
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]54- Classic classes are a thing of the past. All classes are new style.
55
56- Exceptions *must* derive from BaseException.
57
58- Integer division always returns a float. The -Q option is no more.
59 All the following are gone:
60 * PyNumber_Divide and PyNumber_InPlaceDivide
61 * __div__, __rdiv__, and __idiv__
62 * nb_divide, nb_inplace_divide
63 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
64 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
65 if we want to re-use __div__ and friends. If we do, it will make
66 it harder to write code for both 2.x and 3.x.)
67
68- 'as' and 'with' are keywords.
69
70- Absolute import is the default behavior for 'import foo' etc.
71
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]72- Removed support for syntax:
73 backticks (`x`), <>
74
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]75- Removed these Python builtins:
76 apply(), coerce(), input(), raw_input()
77
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]78- Removed these Python methods:
79 {}.has_key
80
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]81- Removed these Python slots:
82 __coerce__, __div__, __idiv__, __rdiv__
83
84- Removed these attributes from Python modules:
85 * operator module: div, idiv, __div__, __idiv__
86
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]87- Removed these C APIs:
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]88 PyNumber_Coerce(), PyNumber_CoerceEx()
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]89
90- Removed these C slots/fields:
91 nb_divide, nb_inplace_divide
92
93- Removed these macros:
94 staticforward, statichere, PyArg_GetInt, PyArg_NoArgs
95
96- Removed these typedefs:
97 intargfunc, intintargfunc, intobjargproc, intintobjargproc,
98 getreadbufferproc, getwritebufferproc, getsegcountproc, getcharbufferproc
99
100- Removed these opcodes:
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]101 BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT
102
103- zip returns an iterator
104
105- Additions:
Georg Brandl66a796e2006-12-19 20:50:34 +0000[diff] [blame]106 set literals, ellipsis literal
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]107
