【问题描述】：

classes = input("There are three types of classes in this game. Warrior, Wizard and Hunter. Pick one.")

if classes == "Warrior" or "Wizard" or "Hunter":
    print ("Good choice.. the "+classes+" will dominate your opponents!")
else:
    print ("That's not a class! Pick again!")

#基本上，我想添加一个循环，以便它会再次提问。

请记住，我使用的是 Python-3

你需要使用while循环，而且or语句是错误的。
