Python os.path是ntpath,怎么样？

Question

谁能告诉我如何Python的"别名" os.path来ntpath？

>>> import os.path
>>> os.path
<module 'ntpath' from 'C:\Python26\lib\ntpath.pyc'>
>>>

Answer 1

看一下os.py,第55-67行:

elif 'nt' in _names:
    name = 'nt'
    linesep = '\r\n'
    from nt import *
    try:
        from nt import _exit
    except ImportError:
        pass
    import ntpath as path

    import nt
    __all__.extend(_get_exports_list(nt))
    del nt

的import ntpath as path是使特定的语句os.path是ntpath在你的平台上(无疑于Windows).

Answer 2

>>> import os as my_aliased_module
>>> my_aliased_module
<module 'os' from 'C:\Program Files\Python 2.6\lib\os.pyc'>

编辑:因为import在Python中是一个简单的声明,你可以做如下的简洁:

import sys

if sys.platform == 'win32':
  import windows_module as my_module
else:
  import unix_module as my_module
