本文教程操作环境:windows7系统、Python 3.9.1,DELL G3电脑。
1、概念
加载模块的时候,系统会在哪些地方寻找此模块。
2、系统默认的模块搜索路径
importsys sys.path属性可以获取路径列表 #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:\\PyCharmCommunityEdition2019.1.1\\helpers\\pydev','D:\\python\\project','D:\\PyCharmCommunityEdition2019.1.1\\helpers\\third_party\\thriftpy','D:\\PyCharmCommunityEdition2019.1.1\\helpers\\pydev','C:\\Users\\user\\.PyCharmCE2019.1\\system\\cythonExtensions','D:\\python\\project\\包管理','D:\\Anaconda3\\envs\\opp\\python37.zip','D:\\Anaconda3\\envs\\opp\\DLLs','D:\\Anaconda3\\envs\\opp\\lib','D:\\Anaconda3\\envs\\opp','D:\\Anaconda3\\envs\\opp\\lib\\site-packages'] D:\python\project\包管理 D:\PyCharmCommunityEdition2019.1.1\helpers\pydev D:\python\project D:\PyCharmCommunityEdition2019.1.1\helpers\third_party\thriftpy D:\PyCharmCommunityEdition2019.1.1\helpers\pydev C:\Users\user\.PyCharmCE2019.1\system\cythonExtensions D:\python\project\包管理 D:\Anaconda3\envs\opp\python37.zip D:\Anaconda3\envs\opp\DLLs D:\Anaconda3\envs\opp\lib D:\Anaconda3\envs\opp D:\Anaconda3\envs\opp\lib\site-packages
3、添加搜索路径
sys.path.append(dir)
