我的基于文本的游戏中的整数检查系统不起作用

Posted 2021-05-06

所以我为我的游戏制作了一个系统，以便我可以检查玩家的输入是否为整数。但由于某种原因，即使我输入一个整数，它也会返回“请输入整数”。我相信它在这里与这个功能有关，其目的是检查玩家输入以及它是否是整数：

def pII(options):
    #PII stands for Player Input Int 
    playerInput = (input("==> "))

    while playerInput != range(1, options):
        print("Please enter an integer")
        playerInput = (input("==>"))  

    while playerInput <= 0 or playerInput > options:
        print("This is not an available option")
        playerInput = int(input("==>"))    

    return(playerInput)

逻辑对我有意义，所以我不明白为什么它不起作用。我没有得到任何错误，所以至少就是这样。无论如何，如果有帮助，这里是我游戏的完整代码。我采取的代码段落来自第15-27行

titleScreen()

答案

问题来自测试playerInput != range(1, options)选项是否正确。这总是返回true，因为playerInput永远不是一个范围。比较应该是：

playerInput not in range(1, options)

将playerInput与范围中的每个值进行比较

请记住，我们还希望将输入作为整数，因此该类变为：

def pII(options):
    #PII stands for Player Input Int 
    playerInput = (input("==> "))

    while playerInput not in  range(0,options):
        print("Please enter an integer")
        playerInput = int(input("==>"))  

    while playerInput <= 0 or playerInput > options:
        print("This is not an available option")
        playerInput = int(input("==>"))    

    return(playerInput)
