Python：Windows中的环境变量

Question

>>> import sys
>>> sys.path
['', '/usr/lib/python27.zip', '/usr/lib/python2.7',
 '/usr/lib/python2.7/plat-cygwin', '/usr/lib/python2.7/lib-tk',
 '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload',
 '/usr/lib/python2.7/site-packages']

question :

I have installed python in windows and set sys path, ithusI can run python with command line but why the sys.path doesn't right, it's like a Linux env path

Answer 1

sys.path is not related to PATH environment variable. It specifies search path for python modules.

You should check os.environ['PATH'] (or os.path.environ.get('PATH') ) to check PATH environment variable.

search paths are looks like linux path because you're using cygwin version of Python, instead of native windows version. (You can find one from Python releases for Windows )
