最近，我开始蟒蛇，并开始制定通过CMD迷你店。这里是我的代码，我试图添加除错误，但我的对齐不好，任何想法我应该可以解决吗？或固定的。什么即时试图在这里做的就是添加ValueError异常，所有Shop_Pasirinkimas = 1,2,3。你也可以看看到所有的如果，否则ELIF功能，并检查他们是很好的。对于这样做，我真的给你多少尊重。对不起，我的英语不好。 P.S我是新来的Python。

你不需要try/except。不要使用int(Shop_Pasirinkimas)，只是比较输入字符串：
while True:
if Shop_Pasirinkimas == "1":
...
elif Shop_Pasirinkimas == "2":
...
elif Shop_Pasirinkimas == "3":
...
else:
print("Enter 1, 2, or 3")
