嗨，

我是python的新手，正在尝试按照Pentesteracademy的建议制作FTP连接器。我正在进行一项运动，似乎运行了几次，然后我得到一个错误说明

"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"

我不确定我错在哪里，但我花了不少时间试图解决这个问题。对不起，如果问题很简单，我只是没有看到它

Answer 1

您的本地模块名称为SELECT tf.filename FROM tempfile，而且正在导入而不是原始队列：

Queue

只需重命名您的File "ftp_login.py", line 4, in <module> from Queue import * File "/media/sf_Python/Pentest/Queue.py", line 22, in <module> ~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^~文件

即可

Answer 2

模块对象不可调用，可能是由于导入/使用错误。

正确的方法是：

from Queue import Queue
q = Queue()

或

import Queue
q = Queue.Queue()

队列模块错误
