TypeError：无法将“ int”对象隐式转换为str

Question 1

我正在尝试编写文本游戏，但是在定义的函数中遇到了一个错误，该错误使您基本上无法在制作角色后花费技能点。最初，该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。

这是我无法正常使用的部分功能的代码：

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

    print("Ok. You're balance is now at " + balanceAfterStrength + " skill points.")

有谁知道如何解决这个问题？谢谢你

Question 2

您不能将链接string到int。您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.")

Question 3

def attributeSelection():
balance = 25
print("Your SP balance is currently 25.")
strength = input("How much SP do you want to put into strength?")
balanceAfterStrength = balance - int(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 " + str(balanceAfterStrength) + " skill points.")
else:
    print("That is an invalid input. Restarting attribute selection.")
    attributeSelection()
