嗨，

我很新的蟒蛇，並試圖建立FTP連接器通過Pentesteracademy的建議。我工作的這似乎數次正確運行的練習，然後我得到一個錯誤，說明

"File "ftp_login.py", line 4, in <module> 
    from Queue import * 
    File "/media/sf_Python/Pentest/Queue.py", line 22, in <module> 
    queue = Queue.Queue() 
TypeError: 'module' object is not callable" 

我不記得我在哪裏出了問題，但我已經花了不少無用的時間想辦法出來。很抱歉，如果這個問題很簡單，我只是沒有看到它

你當地的模塊命名Queue，它是正在進口的，而不是原來的隊列：

File "ftp_login.py", line 4, in <module> 
    from Queue import * 
    File "/media/sf_Python/Pentest/Queue.py", line 22, in <module> 
     ~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^~ 

只需重命名/media/sf_Python/Pentest/Queue.py文件
