Python os.path is ntpath, how?
提问by Alex Martelli
Can someone tell me how Python "aliases" os.pathto ntpath?
有人能告诉我 Python 是如何“别名”os.path的ntpath吗？
>>> import os.path
>>> os.path
<module 'ntpath' from 'C:\Python26\lib\ntpath.pyc'>
>>>

Look at os.py, lines 55-67:
查看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
The import ntpath as pathis the specific statement that causes os.pathto be ntpathon your platforms (doubtlessly Windows).
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）。

>>> import os as my_aliased_module
>>> my_aliased_module
<module 'os' from 'C:\Program Files\Python 2.6\lib\os.pyc'>
EDIT:And since importis a simple statement in Python, you can do neat stuff like:
编辑：由于import是 Python 中的一个简单语句，您可以执行以下操作：
import sys
if sys.platform == 'win32':
import windows_module as my_module
else:
import unix_module as my_module
