本文實例為大家分享了程序:Python購物車程序,具體內(nèi)容如下
需求:
- 啟動程序后,讓用戶輸入工資,然后打印商品列表
- 允許用戶根據(jù)商品編號購買商品
- 用戶選擇商品后,檢測余額是否夠,夠就直接扣款,不夠就提醒
- 可隨時退出,退出時,打印已購買商品和余額
- 如余額不足,可充值
代碼:

salary = int(input("Please input your salary: "))
shoppingmart = []
items = (["1","Huawei","¥",2800],
["2","Earphone","¥",300],
["3","Book","¥",80])
msg_items = '''
----------items----------
1. Huawei ¥ 2800
2. Earphone ¥ 300
3. Book ¥ 80
-------------------------
'''
print(msg_items)
while True:
shopindex = int(input("Please choose goods: "))
if salary > items[shopindex-1][3]:
shoppingmart.append(items[shopindex-1])
salary -= int(items[shopindex-1][3])
print("You have bought {name} !".format(name = items[shopindex-1][1]))
print("Your balance is: ¥",salary)
decision = input("Do you want to quit now?")
print(msg_items)
else:
print("Your balance is not enough! Please try sth else.")
recharge_ans = input("Do you want to recharge?")
if recharge_ans == "y":
recharge = int(input("Please input money: "))
print("Please wait for a while...")
salary += recharge
print("You have recharged successfully!")
print("And the balance is: ",salary,"now!")
decision = input("Do you want to quit now?")
print(msg_items)
if decision == "q":
break
else:
continue
print("You have bought: ",shoppingmart)
print("Your balance is: ¥",salary)
print("Welcome your next coming!")
程序效果:
Please input your salary: 0 ----------items---------- 1. Huawei ¥ 2800 2. Earphone ¥ 300 3. Book ¥ 80 ------------------------- Please choose goods: 1 Your balance is not enough! Please try sth else. Do you want to recharge?y Please input money: 30000 Please wait for a while... You have recharged successfully! And the balance is: 30000 now! Do you want to quit now? ----------items---------- 1. Huawei ¥ 2800 2. Earphone ¥ 300 3. Book ¥ 80 ------------------------- Please choose goods: 1 You have bought Huawei ! Your balance is: ¥ 27200 Do you want to quit now? ----------items---------- 1. Huawei ¥ 2800 2. Earphone ¥ 300 3. Book ¥ 80 ------------------------- Please choose goods: 2 You have bought Earphone ! Your balance is: ¥ 26900 Do you want to quit now?q ----------items---------- 1. Huawei ¥ 2800 2. Earphone ¥ 300 3. Book ¥ 80 ------------------------- You have bought: [['1', 'Huawei', '¥', 2800], ['2', 'Earphone', '¥', 300]] Your balance is: ¥ 26900 Welcome your next coming!
