当我使用这个程序时，无论我在pythonshell中输入什么，它都会一遍又一遍地说同样的话。。它不会将原始的输入语句放到上下文中，并将它们放入if语句中

Answer 1

这里的语法错误：

if Enter == "Yes" or "yes":

这个条件永远是真的。Enter == "Yes"首先计算。如果布尔表示是False，则将考虑"yes"的布尔表示。bool("yes")总是{}。在

考虑做一些类似的事情：

^{pr2}$

或者：

if Enter.lower() == 'yes':

Answer 2

if Enter == "Yes" or "yes":

这不是or的工作方式。这被解释为if (Enter == "Yes") or "yes":。在python中，非空字符串始终为true，因此所有类似的if语句都将为true。我建议你

^{pr2}$

它处理所有的大写/小写组合。在
