python print the specified location, the absolute path for all files and directories

Requirements: Given a path, to print out all the paths (the path is not until the next directory up)

Import OS 
path_list = []
 DEF get_all (path):
     # path = r'D: \ the Test3 ' 
    Paths = the os.listdir (path) # lists all the directories and files in the specified directory 
    for I in Paths: 
        com_path = OS. path.join (path, i)
         # Print (com_path) 
        IF os.path.isdir (com_path): 
            get_all (com_path) # If the path is a directory, calls itself the method 
        elif os.path.isfile (com_path): 
            path_list. the append (com_path) # If the path is a file, appended to the path_list 
            # print (com_path) print each file absolute path 
        print(com_path) # print the absolute path of all files and directories 
Print ( " D: \ Test3 includes the following files: " )
 # call the function 
get_all (r = path ' D: \ Test3 ' )
