TypeError:无法将“int"对象隐式转换为str

问题描述

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，该函数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.显然这是错误的，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)，我对它到底是什么感到困惑正试图告诉我以及我如何解决它.

I am trying to write a text game and I have run into an error in the function I am defining that lets you basically spend your skill points after you make your character. At first, the error stated that I was attempting to subtract a string from an integer in this part of the code:balance - strength. Obviously that was wrong so I fixed it with strength = int(strength)... but now I am getting this error which I have never seen before(new programmer) and I am stumped on what exactly it is trying to tell me and how I fix it.

这是我的代码，用于部分功能不起作用:

Here is my code for the part of the function that isn't working:

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:

And here is the error I get when I get to this part of the code in the shell:

    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?先谢谢了.

Does anyone know how to solve this? Thanks ahead.

推荐答案

您不能将 string 与 int 连接.您需要使用 str 函数将 int 转换为 string，或使用 formatting 格式化输出.

You cannot concatenate a string with an int. You would need to convert your int to a string using the str function, or use formatting to format your output.

更改:-

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

到:-

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

或:-

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

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

or as per the comment, use , to pass different strings to your print function, rather than concatenating using +: -

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