計算旅費的練習

def hotel_cost(nights):   # 每晚旅館費用140元
  return 140 * nights

def plane_ride_cost(city):    # 不同城市的機票錢
  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):    # 每天租車費用與折扣
  total = 40 * days
  if days >= 7:
    total -= 50
  elif days >= 3:
    total -= 20
return total

# 利用所有已經設定之方程式，計算旅費總額
# spending_money為額外支出

def trip_cost(city,days,spending_money):
  return rental_car_cost(days) + hotel_cost(days) + plane_ride_cost(city) + spending_money

# 飛洛杉磯5天，額外支出600元

print(trip_cost("Los Angeles",5,600))    

本次旅費總共 = 1955元

自我練習: 計算之前去日本旅遊的大概費用

def hotel(nights):    # 住宿每天約845元台幣
  return 845 * nights

def plane_ticket_go(city_go):    # 去程機票
  if city_go == "Tokyo":
    return 3978

def plane_ticket_back(city_back):    # 回程機票(包含不同機場價格)
  if city_back == "Tokyo":
    return 5779
  elif city_back == "Osaka":
    return 12660 * 0.272               # 當時匯率約 0.272

def trip_cost(city_go,city_back,nights,spending_money):   # 旅費總額計算(額外支出設定日幣->台幣)
  spending_money = spending_money * 0.272
  return hotel(nights) + plane_ticket_go(city_go) + plane_ticket_back(city_back) + spending_money

# 東京進出，8晚，額外支出設定10萬

print('案例1-總花費:')
print(trip_cost("Tokyo","Tokyo",8,100000))

# 東京進，大阪出，33晚，額外支出設定30萬

print('案例2-總花費:')
print(trip_cost("Tokyo","Osaka",33,300000))

案例1-總花費:
43717.0
案例2-總花費:
116906.52
