Python-TypeError：无法将“ int”对象隐式转换为str

我正在尝试编写文本游戏，但在定义的函数中遇到了错误，该错误使你基本上无法在制作角色后花费技能点。最初，错误表明我正在尝试从代码的这一部分的整数中减去一个字符串balance - strength。显然这是错误的，所以我用strength = int(strength)… 修复了它，但是现在我遇到了一个以前从未见过的错误（新程序员），并且我对确切要告诉我的内容以及如何解决它感到困惑。

这是我的部分功能不起作用的代码：

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()

这是我在shell中获得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

有谁知道如何解决这个问题？谢谢你

回答：

你不能将链接string到int。你需要使用函数将转换int为，或使用格式化输出。stringstrformatting

变更：

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

至： 

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

要么： 

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

或根据注释，用于,将不同的字符串传递给print函数，而不是使用+：- 串联

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