TypeError an 'int' object cannot be implicitly converted to str

我正在尝试编写一个文本游戏，我在我定义的函数中遇到了一个错误，错误表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。显然这是错误的，所以我用strength = int(strength)... 修复它但是现在我得到了这个我以前从未见过的错误（新程序员）。
这是我的函数部分无法正常工作的代码：
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得到的错误：
    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。

不能用int连接一个string。您需要使用str函数将您转换int为str，或使用格式化输出。Stringstrformatting
将
print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")
变成
print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))
或者
print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")
或者根据注释，用于,将不同的字符串传递给您的print函数，而不是使用+方法连接：
print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")
