python recursive directory traversal

OS Import 

DEF getAllDirRE (path, SP = ""): 
    # get all the files in the current directory 
    filesList the os.listdir = (path) 
    # process each file 
    SP + = "" 
    for fileName in filesList: 
        # determines whether the path ( absolute path) 
        fileAbsPath = os.path.join (path, fileName) 
        IF os.path.isdir (fileAbsPath): 
            Print (SP + "directory:", fileName) 
            # recursive call 
            getAllDir (fileAbsPath, SP) 
        the else: 
            Print ( sp + "Trivial file:", fileName)
