Python列表幫助：TypeError：無法連接'str'和'list'對象

我正在製作主桌面的列表，以便讀取哪些圖標是可執行的，哪些不是。我不斷收到錯誤：類型錯誤：不能連接「海峽」和「名單」對象Python列表幫助：TypeError：無法連接'str'和'list'對象

下面是代碼樣本：是的，我已經嘗試一切，它只是不想要的工作。

list0 = ["","","","","","","","","","","","","","","","","","","","","","","","","","","","","","","",""] 
    for filee in fls: 
     if filee.endswith(".jex"): 
      jkjk = filee 
      icon = os.listdir("/Users/"+getpass.getuser()+"/Desktop/"+jkjk+"/Files/Icon") 
      for anything in icon: 
       if anything.endswith(".png"): 
        fttts = pygame.image.load("/Users/"+getpass.getuser()+"/Desktop/"+jkjk+"/Files/Icon/"+anything) 
        fttts = pygame.transform.scale(fttts, (48, 48)) 
        screen.blit(fttts, (15+aaas, 295+fasdd)) 
        print("aaas = "+str(aaas)) 
        print("fasdd = "+str(fasdd)) 
        fasdd = fasdd + 45 

        if fasdd >= winy-295-63: 
         aaas = aaas + 63 
         fasdd = -280 
      jkjk = jkjk+"/Files/Executable" 
      jkjk = os.listdir("/Users/"+getpass.getuser()+"/Desktop/"+jkjk) 
      for exfilepy in jkjk: 
       if exfilepy.endswith(".py"): 
        for o in os.listdir("/Users/"+getpass.getuser()+"/Desktop/"+jkjk+execfilepy): 
         ftttThis[o] = [str(os.listdir("/Users/"+getpass.getuser()+"/Desktop/"+jkjk+execfilepy)[o])] 
        for i in list0: 
         list0[i] = ftttThis[i]

.jex是自定義擴展名，並不會導致問題。這是名單。

輸出：

Traceback (most recent call last):

    top().top()

    setup().setdesk() 
    File "/Users/kf9z/Desktop/JupeeGUIFiles 2/JUPEE_GUI_WINDOWS copy.py", line 191, in setdesk 
    for o in os.listdir("/Users/"+getpass.getuser()+"/Desktop/"+jkjk+execfilepy): 
TypeError: cannot concatenate 'str' and 'list' objects

這是Python 2.7版（或2.X）

它實際上不是告訴哪些並且是不可執行的，它告訴它 – MezuCobalt

而不是創造空字符串列表的創建一個* empty *列表並使用'lis0.append（）'添加新元素。 –

它告訴它：因爲無論桌面上有多少額外的圖標：轉到list0 []查找圖標指向的目錄至。 – MezuCobalt

你改變了jkjk在這裏的列表：

jkjk = os.listdir("/Users/"+getpass.getuser()+"/Desktop/"+jkjk)

然後你想串連它到一個字符串：

os.listdir("/Users/"+getpass.getuser()+"/Desktop/"+jkjk+execfilepy):

如果你想在原來的jkjk則列表分配到一些新的變量：

jkjk = jkjk+"/Files/Executable" 
lis = os.listdir("/Users/"+getpass.getuser()+"/Desktop/"+jkjk) 
for exfilepy in lis: 
    #your code
