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,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如何修复它.
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 …如果我尝试执行以下操作:
things = 5
print("You have " + things + " things.")
我在Python 3.x中收到以下错误:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: must be str, not int
......以及Python 2.x中的类似错误:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot concatenate 'str' and 'int' objects
我怎样才能解决这个问题？
