如何定义一个接受权重并输出价格的函数
如何定义一个接受权重并输出价格的函数
提问于 2021-11-18 19:01:45
我想添加一个接受权重和输出成本的def函数，但我不知道如何使用if elif循环
weight = float(input("Enter package weight: ")) #package weight
cost_ground_premium = 125.00 #flat charge for premium
if weight <= 2: #package weighs 2 lb or less
cost_ground = weight * 1.50 + 20 # $1.50/lb, flat charge of $20
elif weight <= 6: #over 2lb but less/equal to 6lb
cost_ground = weight * 3.00 + 20 # $3/lb + flat charge
elif weight <= 10: #over 6lb but less/equal to 10lb
cost_ground = weight * 4.00 + 20 # $4/lb + flat charge
else: #over 10lb
cost_ground = weight * 4.75 + 20 # $4.75/lb + flat charge
print("Ground Shipping $", round(cost_ground, 2))
print("Ground Shipping Premium $", round(cost_ground_premium, 2))
drone_weight = float(input("Enter package weight if using Drone Shipping: "))
if drone_weight <= 2: # $4.50/lb. No flat charge
cost_drone = drone_weight * 4.50 #no flat charge
elif drone_weight <= 6: # $9/lb
cost_drone = drone_weight * 9.00
elif drone_weight <= 10: # $12/lb
cost_drone = drone_weight * 12.00
else: # $14.25/lb
cost_drone = drone_weight * 14.25
print("Drone Shipping $", round(cost_drone, 2))回答 5

将您的整个逻辑封装在def中，但输入除外
def calculateCost():初始化weight=1，然后使用while循环。
while weight!=0:
weight = float(input("Enter package weight: "))
calculateCost(weight)还要确保在函数中，如果weight为0，它就会通过。

您需要将cost_ground和cost_drone从if和elif块中删除。下面我将为你的代码编写函数和循环。
def func(weight, drone_weight):
cost_ground = None
cost_drone = None
cost_ground_premium = 125.00 #flat charge for premium
if weight <= 2: #package weighs 2 lb or less
cost_ground = weight * 1.50 + 20 # $1.50/lb, flat charge of $20
elif weight <= 6: #over 2lb but less/equal to 6lb
cost_ground = weight * 3.00 + 20 # $3/lb + flat charge
elif weight <= 10: #over 6lb but less/equal to 10lb
cost_ground = weight * 4.00 + 20 # $4/lb + flat charge
else: #over 10lb
cost_ground = weight * 4.75 + 20 # $4.75/lb + flat charge
if drone_weight <= 2: # $4.50/lb. No flat charge
cost_drone = drone_weight * 4.50 #no flat charge
elif drone_weight <= 6: # $9/lb
cost_drone = drone_weight * 9.00
elif drone_weight <= 10: # $12/lb
cost_drone = drone_weight * 12.00
else: # $14.25/lb
cost_drone = drone_weight * 14.25
return (round(cost_ground, 2), round(cost_drone, 2), cost_ground_premium)
while 1:
weight = float(input("Enter package weight: ")) #package weight
if weight == 0:
break
drone_weight = float(input("Enter package weight if using Drone Shipping: "))
cost_ground, cost_drone, cost_ground_premium = func(weight, drone_weight)
print("Ground Shipping $", cost_ground)
print("Ground Shipping Premium $", cost_ground_premium)
print("Drone Shipping $", cost_drone)Stack Overflow用户

weight = float(input("Enter package weight: ")) #package weight
cost_ground_premium = 125.00 #flat charge for premium
def get_cost_ground(weight, flat_charge=20, is_premimum=False):
# flat charge for premium
if is_premimum:
return cost_ground_premium
if weight <= 2: #package weighs 2 lb or less
cost_ground = weight * 1.50 + flat_charge # $1.50/lb, flat charge of $20
elif weight <= 6: #over 2lb but less/equal to 6lb
cost_ground = weight * 3.00 + flat_charge # $3/lb + flat charge
elif weight <= 10: #over 6lb but less/equal to 10lb
cost_ground = weight * 4.00 + flat_charge # $4/lb + flat charge
else: #over 10lb
cost_ground = weight * 4.75 + flat_charge # $4.75/lb + flat charge
return cost_ground 然后使用get_cost_ground(weight)调用。用于高级调用方法get_cost_ground(weight,is_premimum=True)。类似地，您可以对无人机运输计算执行此操作
