如何在本例中将变量传递给函数？

Question

我写了一个非常基本的脚本来清理我的下载文件夹，一切正常，但我没有使用任何功能。

为了清理一些东西，并使其更加有组织，我尝试创建函数并将目录路径作为变量“清理路径”传递，但我认为我做了一些不正确的事情。

import sys 
import os 
from os import listdir 
from os.path import join 
import shutil 


#Variables 
path="/Users/OwlFace/downloads" 
cleaningpath=os.listdir(path) 


def deleterars(cleaningpath): 
    rarcounter=0 
    for item in cleaningpath: 
     if item.endswith(".rar"): 
      os.remove(join(cleaningpath,item)) 
      rarcounter+=1 
    print "you have succesfully removed", rarcounter, "rar files" 


def organizemusic(cleaningpath): 
    mp3counter=0 
    if not os.path.exists("/Users/OwlFace/downloads/NewMusic/"): 
     os.makedirs("/Users/OwlFace/downloads/NewMusic/") 
    mp3folder="/Users/OwlFace/downloads/NewMusic/" 

    for item in cleaningpath: 
     if item.endswith(".mp3"): 
      location1 = join(cleaningpath,item) 
      location2 = join(mp3folder,item) 
      shutil.move(location1, location2) 
      mp3counter+=1 
    print "you have succesfully moved", mp3counter, "mp3's to the music folder" 


if __name__ == "__main__": 
    deleterars(cleaningpath) 
    organizemusic(cleaning path) 

错误：

Traceback (most recent call last): 
    File "cleaningscript.py", line 39, in <module> 
    organizemusic(cleaningpath) 
    File "cleaningscript.py", line 30, in organizemusic 
    location1 = join(cleaningpath,item) 
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/posixpath.py", line 70, in join 
    elif path == '' or path.endswith('/'): 
AttributeError: 'list' object has no attribute 'endswith'

错误指的是线路：

location1 = join(cleaningpath,item) 

此行不起作用，因为cleaningpath是文件名，而不是字符串列表。我想你想要你的全局变量path作为join的第一个参数。

您的其他功能同样的问题，在这条线：

  os.remove(join(cleaningpath,item))
