Python 为什么我的输入不打印（作为参数输入）？

这是我的代码：

def totalPrice(meal, tip):
    meal = input("What was your total meal price?")
    tip = input("What would you like to tip?")

    total_bill = meal * (tip/100) + meal
    return total_bill

 print(totalPrice(meal,tip))

当我运行它时，什么也没发生。我很好奇，为什么我的输入没有在控制台中打印，错误发生在哪里。

因为你把一个字符串除掉了。将字符串转换为浮点数，如果不使用，则删除参数：

def totalPrice():
    meal = float(input("What was your total meal price?"))
    tip = float(input("What would you like to tip?"))

    total_bill = meal * (tip/100) + meal
    return total_bill

 print(totalPrice())

或者将参数移出函数：

def totalPrice(meal, tip): 
  total_bill = meal * (tip/100) + meal
  return total_bill

meal = float(input("What was your total meal price? "))
tip = float(input("What would you like to tip? "))
print(totalPrice(meal, tip))

最后，一切正常

What was your total meal price? 1
What would you like to tip? 2
1.02

我认为那里有一些代码错误。不需要在函数中接收变量和提示，因为您是从其中的输入创建它们的。您还必须将输入转换为float才能进行数学运算。试试这个：

def totalPrice():
    meal = float(input("What was your total meal price? "))
    tip = float(input("What would you like to tip? "))

    total_bill = meal * (tip/100) + meal
    return total_bill

print(totalPrice())

问题是您所输入的是字符串类型&存在一些缩进错误

int类型的语法是

variable_name=int(input(" "))

试试这个

def totalPrice(meal, tip):
    total_bill = meal * (tip/100) + meal
    return total_bill

meal = int(input("What was your total meal price?"))
tip = int(input("What would you like to tip?"))
res=totalPrice(meal,tip)
print(res)

您可以使用以下选项：

meal = int(input("What was your total meal price?"))
tip = int(input("What would you like to tip?"))
def totalPrice(meal, tip):
    total_bill = meal * (tip/100) + meal
    return total_bill
print (totalPrice(meal,tip))

或者这个：

def totalPrice():
    meal = int(input("What was your total meal price?"))
    tip = int(input("What would you like to tip?"))


    total_bill = meal * (tip/100) + meal
    return total_bill

print (totalPrice())

您的代码有缩进错误。你需要发布一个缩进错误，这样我们就可以运行你的代码了？！可能是重复的哦，我明白了！非常感谢。
