Question

我正在尝试编写一个文本游戏，我在定义的函数中遇到了一个错误，让你在制作角色后基本上可以花费你的技能点数。起初，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）而且我很难说它到底想要告诉我什么以及我是怎么回事解决它。

以下是我无法正常工作的部分代码：

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

    print("Ok. You're balance is now at " + balanceAfterStrength + " skill points.")
TypeError: Can't convert 'int' object to str implicitly

有谁知道如何解决这个问题？谢谢。

Answer 1

您无法将string与int连接起来。您需要使用int功能将string转换为str，或使用formatting格式化输出。

更改： -

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

来： -

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print函数，而不是使用+连接： -

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

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()

TypeError：无法隐式地将'int'对象转换为str
