We support many built-in functions (Python 2, Python 3), but not all of them. Some of these need some more discussion (i.e. what about builtins that exist in Python 2 but not 3 and vice versa), but many can be done piecemeal and should be straightforward to implement. When you implement a builtin please check to see if it is a magic method.

To do

• abs()
• all()
• any()
• bin()
• bool()
• bytearray()
• chr()
• dict()
• divmod()
• enumerate()
• float()
• getattr()
• hash()
• hex()
• int()
• isinstance()
• len()
• list()
• long() (long is deprecated in py3 builtins)
• max()
• min()
• oct()
• ord()
• pow()
• print()
• range()
• reversed()
• round()
• set()
• slice()
• sorted() (separate issue, implemented for lists)
• str()
• sum()
• type()

Maybe to do later (when things like first class modules are in, or if we ever have something like iterators)

• callable()
• tuple()
• complex()
• delattr()
• filter()
• format()
• frozenset()
• globals()
• hasattr()
• issubclass()
• iter()
• locals()
• next()
• object()
• property()
• reduce()
• setattr()
• repr()
• super()
• vars()
• zip()

Probably won't do

• __import__()
• basestring()
• classmethod()
• cmp()
• compile()
• dir()
• eval()
• execfile()
• file()
• help()
• id()
• input()
• map()
• memoryview()
• open()
• raw_input()
• reload()
• staticmethod()
• unichr()
• unicode()
• xrange()
