从命令行运行python -v应该会告诉你导入了什么以及从哪里导入。这在Windows和Mac OS X上都适用。

C:\>python -v

# installed zipimport hook

在python解释器中，您可以导入特定的模块，然后键入help(module)。这将提供诸如名称、文件、模块文档、描述等详细信息。

Ex:

help(os)


Help on module os:

Python 3.2中的新功能，你现在可以使用dis模块中的code_info(): http://docs.python.org/dev/whatsnew/3.2.html#dis

下面是一行代码获取模块的文件名，适用于shell别名:

echo 'import sys; t=__import__(sys.argv[1],fromlist=[\".\"]); print(t.__file__)'  | python - 

设置为别名:

alias getpmpath="echo 'import sys; t=__import__(sys.argv[1],fromlist=[\".\"]); print(t.__file__)'  | python - "

使用方法:

$ getpmpath twisted
/usr/lib64/python2.6/site-packages/twisted/__init__.pyc
$ getpmpath twisted.web
/usr/lib64/python2.6/site-packages/twisted/web/__init__.pyc

如果使用pip来安装模块，只需返回pip show $module位置。
