简单的RPS程序。程序现在正在运行，除了再次播放的提示，但之后它会抛出错误。这些是我回来的错误：

欢迎任何有用的输入！

Answer 1

player_choice=input("Please enter a menu selection:")
while player_choice >3 or player_choice < 1:

在Python 3.X中，input返回一个字符串，您无法将字符串与整数进行比较。在分配之前将值转换为int。

player_choice=int(input("Please enter a menu selection:"))
while player_choice >3 or player_choice < 1:
