Question

我正在制定一个虐待/欺凌意识计划（例如，告诉他人），您可以在其中选择问题和位置，然后输入名称并按提交。但是，我为Submit函数编写的代码没有注册任何输入。

我切换到“提交”按钮，因为以前的修订版难以为新用户使用。

我正在尝试让程序在按下按钮时将一些信息打印到终端中，但此刻它只是创建换行符。

您永远不会调用会设置变量b的函数受害者（）或perp（），因此x值始终为3并执行打印。

还可以将global b放在受害者和perp两个函数中，否则b将是局部的。

一些建议对字符串“受害者”和“犯罪者”使用常量：

VICTIM = "Victim"
PERPETRATOR = "Perpetrator"

对变量的命名也要比x或b（也许是person_kind）更好。您还可以删除if b == ...然后设置x，然后只使用person_kind（或您选择的任何好听的名字）

if person_kind == VICTIM:
    ... do something for Victim
elif person_kind == PERPETRATOR:
    ... do something for Perpetrator

以此类推

如果可能，还尝试避免使用全局变量。祝你好运
