TypeError：无法将‘int’对象隐式转换为str

TypeError：无法将‘int’对象隐式转换为str

我正在尝试写一个文字游戏，我在我定义的函数中遇到了一个错误，这个函数让你在完成角色后基本上可以使用你的技能点。首先，错误声明我试图从代码的这一部分中的整数中减去一个字符串：balance - strength..显然那是错误的，所以我用strength = int(strength)..但是现在我得到了这个错误，这是我以前从未见过的(新程序员)，我很困惑它到底想告诉我什么，以及我是如何修复它的。

下面是函数中不起作用的部分的代码：

def attributeSelection():
    balance = 25
    print("Your SP balance is currently 25.")
    strength = input("How much SP do you want to put into strength?")
    strength = int(strength)
    balanceAfterStrength = balance - strength    if balanceAfterStrength == 0:
        print("Your SP balance is now 0.")
        attributeConfirmation()
    elif strength < 0:
        print("That is an invalid input. Restarting attribute selection. Keep an eye on your balance this time!")
        attributeSelection()
    elif strength > balance:
        print("That is an invalid input. Restarting attribute selection. Keep an eye on your balance this time!")
        attributeSelection()
    elif balanceAfterStrength > 0 and balanceAfterStrength < 26:
        print("Ok. You're balance is now at " + balanceAfterStrength + " skill points.")
    else:
        print("That is an invalid input. Restarting attribute selection.")
        attributeSelection()

有人道怎么解决这个问题吗？先谢了。
