为什么我的代码会提出typeError异常

Question

当我运行以下代码时：

 while start == "yes":
    player1name = input("Player 1 what shall your character be called?")
    player2name = input("Player 2 what shall your character be called?")
    player1strength=print("Player 1,your strength score is :)", random.randint(1,7))
    player2strength=print("Player 2,your strength score is :)", random.randint(1,7))
    strengthdifference =(int(player1strength) - int(player2strength))
    if strengthdifference<0:
        strengthdifference=player2strength-player1strength
        strengthdifference=strengthdifference/5
        player1skill=int(input("Player 1,enter your skill score :)"))
        player2skill=int(input("Player 2,enter your skill score :)"))
        skilldifference=player1skill-player2skill

我得到了这个追溯：

File "C:ComputingA453 AssessmentTask 3main.py", line 18, in <module>
    strengthdifference =(int(player1strength) - int(player2strength))
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

我在做什么错？如何解决错误？

Answer 1

错误说他们的 player1strength或 player2strength（或可能两者）是 None， int()不能将其作为参数。这可能是 is 兼有，因为您将调用print的结果分配给每个。

。

也许 it 确实说了一些关于 *强度差异的信息，但是由于您没有提供细节，我无法对此做出回应。
