我正在尝试编写一个文本游戏，但我在定义的函数中遇到了一个错误，它让你在制作角色后基本上可以花费你的技能点。起初，错误表明我试图在这部分代码中从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)...修复了它，但现在我遇到了这个我以前从未见过的错误（新程序员），我很难理解它到底想告诉我什么以及我如何修复它。

这是我的代码不起作用的部分功能：

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()

这是我在 shell 中访问这部分代码时遇到的错误：

    Your SP balance is currently 25.
How much SP do you want to put into strength?5

    print("Ok. You're balance is now at " + balanceAfterStrength + " skill points.")
TypeError: Can't convert 'int' object to str implicitly

有谁知道如何解决这个问题？提前谢谢。

您不能将 astring与连接起来int。您需要使用该函数将您的转换int为 a ，或用于格式化您的输出。stringstrformatting

改变： -

print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")

到： -

print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))

或者： -

print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")

或根据评论，用于,将不同的字符串传递给您的print函数，而不是使用连接+： -

print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")
