如何在本例中將變量傳遞給函數？

Question

我寫了一個非常基本的腳本來清理我的下載文件夾，一切正常，但我沒有使用任何功能。

爲了清理一些東西，並使其更加有組織，我嘗試創建函數並將目錄路徑作爲變量「清理路徑」傳遞，但我認爲我做了一些不正確的事情。

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) 

錯誤：

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'

錯誤指的是線路：

location1 = join(cleaningpath,item) 

此行不起作用，因爲cleaningpath是文件名，而不是字符串列表。我想你想要你的全局變量path作爲join的第一個參數。

您的其他功能同樣的問題，在這條線：

  os.remove(join(cleaningpath,item))
