Python 如何制作用户定义的函数变量?
我有这样的代码:Python 如何制作用户定义的函数变量?,python,python-3.x,function,input,Python,Python 3.x,Function,Input,我有这样的代码: def hotel_cost(nights): return 140 * nights def plane_ride_cost(city): if city == "Charlotte": return 183 elif city == "Tampa": return 220 elif city == "Pittsburgh": return 222 elif city == "Los A
def hotel_cost(nights):
return 140 * nights
def plane_ride_cost(city):
if city == "Charlotte":
return 183
elif city == "Tampa":
return 220
elif city == "Pittsburgh":
return 222
elif city == "Los Angeles":
return 475
def rental_car_cost(days):
cost = 40 * days
if days >= 7:
cost -= 50
elif days >= 3:
cost -= 20
return cost
def trip_cost(city, days, spending_money):
return plane_ride_cost(city) + rental_car_cost(days) + hotel_cost(days) + spending_money
print (trip_cost("Tampa", 2, 200))
我知道我需要使用input()使所有4个变量(夜晚、城市、白天、花销)都由用户定义。但具体是怎样的呢?试试这个开始:
a = input("Town:\n")
b = int(input("Days:\n"))
c = int(input("Money:\n"))
print (trip_cost(a, b, c))
首先看一下
input
函数:-)我已经做过了。我在每个函数定义之前放了4个“输入”,但我仍然不知道在代码末尾键入什么…这就是重点。最后一行解决了我的问题。谢谢!
