这篇文章主要介绍怎么使用python3代码查看包的路径，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
当你使用 import 导入一个包或模块时，Python 会去一些目录下查找，而这些目录是有优先级顺序的，正常人会使用 sys.path 查看。
>>> import sys >>> from pprint import pprint >>> pprint(sys.path) ['', '/usr/local/Python3.7/lib/python37.zip', '/usr/local/Python3.7/lib/python3.7', '/usr/local/Python3.7/lib/python3.7/lib-dynload', '/home/wangbm/.local/lib/python3.7/site-packages', '/usr/local/Python3.7/lib/python3.7/site-packages'] >>>
那有没有更快的方式呢？
我这有一种连 console 模式都不用进入的方法呢？
你可能会想到这种，但这本质上与上面并无区别
[wangbm@localhost ~]$ python -c "print('\n'.join(__import__('sys').path))"
/usr/lib/python2.7/site-packages/pip-18.1-py2.7.egg
/usr/lib/python2.7/site-packages/redis-3.0.1-py2.7.egg
/usr/lib64/python27.zip
/usr/lib64/python2.7
/usr/lib64/python2.7/plat-linux2
/usr/lib64/python2.7/lib-tk
/usr/lib64/python2.7/lib-old
/usr/lib64/python2.7/lib-dynload
/home/wangbm/.local/lib/python2.7/site-packages
/usr/lib64/python2.7/site-packages
/usr/lib64/python2.7/site-packages/gtk-2.0
/usr/lib/python2.7/site-packages这里我要介绍的是比上面两种都方便的多的方法，一行命令即可解决
[wangbm@localhost ~]$ python3 -m site sys.path = [ '/home/wangbm', '/usr/local/Python3.7/lib/python37.zip', '/usr/local/Python3.7/lib/python3.7', '/usr/local/Python3.7/lib/python3.7/lib-dynload', '/home/wangbm/.local/lib/python3.7/site-packages', '/usr/local/Python3.7/lib/python3.7/site-packages', ] USER_BASE: '/home/wangbm/.local' (exists) USER_SITE: '/home/wangbm/.local/lib/python3.7/site-packages' (exists) ENABLE_USER_SITE: True
从输出你可以发现，这个列的路径会比sys.path更全，它包含了用户环境的目录。
