python内置函数源码_python如何查看内置函数源码
如題，如何查看python內置函數的源碼
舉個例子：
# 該以什么樣的方式，才能去看xrang的官方源碼實現
for i in xrange(10):
print i
# 直接點進去的話，大多都是一些定義的方法名，而沒有具體實現
# 就是想知道，如何去看具體實現，而不是下面那一堆 pass
class xrange(object):
"""
xrange(stop) -> xrange object
xrange(start, stop[, step]) -> xrange object
Like range(), but instead of returning a list, returns an object that
generates the numbers in the range on demand. For looping, this is
slightly faster than range() and more memory efficient.
"""
def __getattribute__(self, name): # real signature unknown; restored from __doc__
""" x.__getattribute__('name') <==> x.name """
pass
def __getitem__(self, y): # real signature unknown; restored from __doc__
""" x.__getitem__(y) <==> x[y] """
pass
def __init__(self, stop): # real signature unknown; restored from __doc__
pass
def __iter__(self): # real signature unknown; restored from __doc__
""" x.__iter__() <==> iter(x) """
pass
def __len__(self): # real signature unknown; restored from __doc__
""" x.__len__() <==> len(x) """
pass
@staticmethod # known case of __new__
def __new__(S, *more): # real signature unknown; restored from __doc__
""" T.__new__(S, ...) -> a new object with type S, a subtype of T """
pass
def __reduce__(self, *args, **kwargs): # real signature unknown
pass
def __repr__(self): # real signature unknown; restored from __doc__
""" x.__repr__() <==> repr(x) """
pass
def __reversed__(self, *args, **kwargs): # real signature unknown
""" Returns a reverse iterator. """
pass
