创建订单记录

order_list = ['rice', 'beef', 'chips', 'pizza', 'pizza', 'yogurt', 'tomato', 'rice', 'beef']

初始化总计金额

total = 0

创建函数order_handle以供后续复用

def order_handle(f_name, price):
    global total
    total += price
    print('%s is %s dollars' % (f_name, price))

进行点餐记录的判断与总计金额打印

for i in order_list:
    if i == 'rice':
        order_handle('rice', 2)
    elif i == 'beef':
        order_handle('beef', 8)
    elif i == 'chips':
        order_handle('chips', 8)
    elif i == 'pizza':
        order_handle('pizza', 10)
    elif i == 'yogurt':
        order_handle('yogurt', 5)
    else:
        order_handle('tomato', 8)
print(total)
