python尋找模塊的路徑順序

>>> import sys
>>> sys.path
['', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/Users/liangshaohua/Library/Python/3.7/lib/python/site-packages', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages']

 python解釋器會從當前目錄開始，從左到右按順序查找。前面的我們基本不用，我們經常用的也就是自己寫的和site-packages,第三方和內置的都在site-packages里面。

 

增加模塊路徑

>>> sys.path.append('module_practice')
>>> import my_module
['', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/Users/liangshaohua/Library/Python/3.7/lib/python/site-packages', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages', 'module_practice']

 

刪除模塊路徑

>>> del sys.path[-1]
>>> sys.path
['', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/Users/liangshaohua/Library/Python/3.7/lib/python/site-packages', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages']

 

注意：增加也只是在當前程序整個程序的運行過程中加了，退出就沒有了。
