Python dynamic import module under a folder

Because there is "user upload script, dynamic Run" needs, so to dynamically import user uploaded modules

So I wrote a function to import dynamically.

#-*-coding:utf-8-*-import osimport sysimport os.pathimport queueimport commandsdef Test (ROOTDIR): #判断传入的路径下是否有 "__i nit__.py "This file is created if not, otherwise the import will not consider this moudle if Os.path.exists (rootdir): arr = Rootdir.spliplit ("/") path Dir = "" for path in Arr:pathdir = Pathdir +path+ "/" If not os.path.exists (pathdir+ "/__init_ _.py "): Commands.getoutput (" Touch "+pathdir+"/__init__.py ") #遍历文件夹找出app_开头的py文件, import, note globals, otherwise the scope is only in this            function under List_dirs = Os.walk (RootDir) for DirName, Subdirlist, fileList in List_dirs:for F in fileList: file_name = f if file_name[0:4] = = "App_" and file_name[-3:] = = ". Py": Imppat H = "" If dirname[-1:]! = "/": Imppath = Dirname.replace ("/", ".") [2:] Else:imppath = Dirname.replace ("/", ".")        [2:-1] Print dirName, "\ n", Imppath if Imppath! = "":            Exe_str = "from" + imppath+ "."                +file_name[0:-3]+ "Import *" Else:exe_str = "from" +file_name[0:-3]+ "Import *" EXEC (Exe_str,globals ()) test ("./app/inapp/") A = Printaa () A.printha ()

./app/inapp/

There's a app_xxx.py file.
