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 Rossum4502c802007-02-09 05:42:38 +0000[diff] [blame^]39- PEP 3105: print is now a function.
40
Brett Cannon398db8b2007-01-29 23:44:37 +0000[diff] [blame]41- PEP 3102: keyword-only arguments.
42
Guido van Rossumec7027f2007-01-30 00:00:40 +0000[diff] [blame]43- Int/Long unification is mostly complete. The 'long' built-in type
44 and literals with trailing 'L' or 'l' have been removed.
45 Performance may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +0000[diff] [blame]46
47- 'except E, V' must now be spelled as 'except E as V' and deletes V
48 at the end of the except clause; V must be a simple name.
49
Neal Norwitzc1505362006-12-28 06:47:50 +0000[diff] [blame]50- Added function annotations per PEP 3107.
51
Georg Brandl66a796e2006-12-19 20:50:34 +0000[diff] [blame]52- Moved intern() to sys.intern().
53
54- exec is now a function.
55
56- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +0000[diff] [blame]57
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]58- Classic classes are a thing of the past. All classes are new style.
59
60- Exceptions *must* derive from BaseException.
61
62- Integer division always returns a float. The -Q option is no more.
63 All the following are gone:
64 * PyNumber_Divide and PyNumber_InPlaceDivide
65 * __div__, __rdiv__, and __idiv__
66 * nb_divide, nb_inplace_divide
67 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
68 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
69 if we want to re-use __div__ and friends. If we do, it will make
70 it harder to write code for both 2.x and 3.x.)
71
72- 'as' and 'with' are keywords.
73
74- Absolute import is the default behavior for 'import foo' etc.
75
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]76- Removed support for syntax:
77 backticks (`x`), <>
78
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]79- Removed these Python builtins:
80 apply(), coerce(), input(), raw_input()
81
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]82- Removed these Python methods:
83 {}.has_key
84
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]85- Removed these Python slots:
86 __coerce__, __div__, __idiv__, __rdiv__
87
88- Removed these attributes from Python modules:
89 * operator module: div, idiv, __div__, __idiv__
90
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]91- Removed these C APIs:
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]92 PyNumber_Coerce(), PyNumber_CoerceEx()
Neal Norwitz4886cc32006-08-21 17:06:07 +0000[diff] [blame]93
94- Removed these C slots/fields:
95 nb_divide, nb_inplace_divide
96
97- Removed these macros:
98 staticforward, statichere, PyArg_GetInt, PyArg_NoArgs
99
100- Removed these typedefs:
101 intargfunc, intintargfunc, intobjargproc, intintobjargproc,
102 getreadbufferproc, getwritebufferproc, getsegcountproc, getcharbufferproc
103
104- Removed these opcodes:
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]105 BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT
106
107- zip returns an iterator
108
109- Additions:
Georg Brandl66a796e2006-12-19 20:50:34 +0000[diff] [blame]110 set literals, ellipsis literal
Neal Norwitz378b2c92006-08-29 07:57:22 +0000[diff] [blame]111
