Python 类型错误：can'；t将序列乘以类型为'的非整数；浮动'；错误I'；我什么都试过了 询问总价、税金和小费。然后将它们相加，得出总价。

我读了很多文章，但我无法修复。有人能帮我吗？

读取的输入是一个字符串，这是一个序列，不能被浮点数乘以

int(price)

解决它。

Python3函数返回一个字符串

您已尝试

float*string+string+string

total= price*percentage + price + tip

TypeError: unsupported operand type(s) for +: 'float' and 'str'

你可以这样修理

from time import sleep 
def getprice():
    return float(input("What's the price of your bill?").lower())

price = getprice()

def gettax():
    return float(input("What's the restaurant's tax percent?").lower())

tax = gettax()

def gettip():
    return float(input("How much tip do you want to leave?"))

tip = gettip()

percentage = tax / 100
total= price*percentage + price + tip

print(total)

是的，你需要把corrs变量转换成int或float。非常感谢，我终于明白我的错误了。我很笨，谢谢！

from time import sleep 
def getprice():
    return float(input("What's the price of your bill?").lower())

price = getprice()

def gettax():
    return float(input("What's the restaurant's tax percent?").lower())

tax = gettax()

def gettip():
    return float(input("How much tip do you want to leave?"))

tip = gettip()

percentage = tax / 100
total= price*percentage + price + tip

print(total)
