本文教程操作环境：windows7系统Python 3.9.1，DELL G3电脑。
1、概念
在加载模块时，系统将在哪里找到该模块。
2、该系统默认模块搜索路径
importsys sys.可以获得路径列表的path属性 #案例p06.py
#案例p06.py importsys print(type(sys.path)) print(sys.path) forpinsys.path: print(p)
<class'list'> ['D:\\python\\project\包管理','D:\PyCharmmunityedition.1\\helpers\\pydev','D:\\python\\project','D:\PyCharmmunityedition.1\\helpers\\third_party\\thriftpy','D:\PyCharmmunityedition.1\\helpers\\pydev','C:\\Users\\user\\.Pycharmce2019.1system\\cythonExtensions','D:\\python\\project\包管理','D:\anaconda3envs\\opp\python377.zip','D:\anaconda3envs\\opp\\DLLs','D:\anaconda3envs\\opp\\lib','D:\anaconda3envs\\opp','D:\anaconda3envs\\opp\\lib\\site-packages'] D:\python\project\包管理 D:2019.19.PyCharmCommunityEdition.1\helpers\pydev D:\python\project D:2019.19.PyCharmCommunityEdition.1\helpers\third_party\thriftpy D:2019.19.PyCharmCommunityEdition.1\helpers\pydev C:\Users\user\.2019年Pycharmcesystem\cythonExtensions D:\python\project\包管理 D:Anaconda3envs\opp\python37.zip D:Anaconda3envs\opp\DLLs D:Anaconda3envs\opp\lib D:Anaconda3envs\opp D:Anaconda3envs\opp\lib\site-packages
3、添加搜索路径
sys.path.append(dir)
以上是python模块搜索路径的介绍，希望能对大家有所帮助。更多Python学习指导：python基础教程
