关于python:typeerror:无法将”int”对象隐式转换为str

TypeError: Can't convert 'int' object to str implicitly

我在写一个文本游戏,我在我定义的函数中遇到了一个错误,这个函数让你基本上在塑造你的角色后花掉你的技能点。起初,错误表明我正试图从代码的这部分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。但是现在我得到了这个我以前从未见过的错误(新程序员),我被它到底要告诉我什么以及如何修复它所困扰。

以下是我对不起作用的函数部分的代码:

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()

下面是我在shell中得到代码的这一部分时得到的错误:

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

有人知道怎么解决这个问题吗?谢谢。


不能将stringint连接起来。您需要使用str函数将int转换为string,或者使用formatting格式化输出。

变化:

1
print("Ok. Your balance is now at" + balanceAfterStrength +" skill points.")

至:

1
print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))

或:

1
print("Ok. Your balance is now at" + str(balanceAfterStrength) +" skill points.")

或者根据注释,使用,将不同的字符串传递给print函数,而不是使用+连接:

1
print("Ok. Your balance is now at", balanceAfterStrength," skill points.")
