我正在制作一个密码检查器和一个带菜单的生成器，密码检查器由它自己工作正常但菜单不能与代码一起工作，我已经通过它尝试了菜单＆＃ 39;自我，这也不起作用。这些是我收到的错误：
Traceback (most recent call last):
File "C:/Users/Jasiu Czajka/PycharmProjects/untitled/First Code.py", line 41, in <module>
mainmenu()
File "C:/Users/Jasiu Czajka/PycharmProjects/untitled/First Code.py", line 24, in mainmenu
passwordchecker()
NameError: name 'passwordchecker' is not defined
我不确定自己做错了什么，所以请尽可能帮忙。
我使用pycharm和python 3.6.3

您需要将调用移至mainmenu()，使其低于passwordchecker()和passwordgenerator()的定义。否则，mainmenu()尝试调用它们时不会定义它们。

似乎你在定义之前调用了一些函数。在mainmenu（）之前放置passwordgenerator（）和passwordchecker（），然后根据需要调用它们。
另外，我可以建议将这个程序放在一个循环中，并且 使该循环依赖于变量。这样会更优雅。其次，将您的功能重命名为：
mainMenu()
passwordGenerator()
passwordChecker()
看起来更专业。祝你好运！
