功能：Python计算价格-抽屉价格答案

【问题标题】：Function:Compute Price in Python- Price of Drawers功能：Python计算价格-抽屉价格
【发布时间】：2016-04-21 09:32:16
【问题描述】：

我要做一个有功能的程序：

接受桌面中抽屉的数量作为键盘的输入。该函数将抽屉的数量返回给 main() 函数。
接受作为输入并返回木材的类型——'m' 代表桃花心木，'o' 代表橡木，或 'p' 代表松木。
以抽屉数量和木材类型为参数，计算书桌成本
显示所有详细信息和最终价格。
一个主函数

我已经有了只有主要功能的成本。我只是不知道如何将它分成四个不同的功能。这是我的代码：

def main(): 

    r = int(input("Enter number of drawers >> ")) #prompting user for input
    extra = 30 * r
    drawers = input("Enter type of wood - m, o, or p >> ") 
    if drawers == 'm':
        ans = 180 + extra
        if r == 1: #if statement
            print("You have ordered a mahogany desk with 1 drawer")
        else:
            print("You have ordered a mahogany desk with",r,"drawers")


    if drawers == 'p':#if statement
        ans = 100 + extra
        if r == 1:#if statement
            print("You have ordered a pine desk with 1 drawer")
        else:
            print("You have ordered a pine desk with",r,"drawers")

    if drawers == 'o':#if statement
        ans = 140 + extra
        if r == 1:#if statement
            print("You have ordered a oak desk with 1 drawer")
        else:
            print("You have ordered a oak desk with",r,"drawers")

    elif drawers == 'o':
        ans = 140 + extra
    elif drawers == 'p':
        ans = 100 + extra
    print("Total price is $"+str(ans)) #printing total price

main()

也许您可以使用这个简单的草图并填写您现有的逻辑：

def drawer_count():
    drawers = int(input("How many drawers?")
    return drawers

def wood_type():
    wood = input("Which type of wood")
    return wood

def calc_price(wood, drawers):
    ...
    return total

def checkout(wood, drawers, total):
    print(...)

def main():
    wood = wood_type()
    drawers = drawer_count()
    total = calc_price(wood, drawers)
    checkout(wood, drawers, total)
