Python 编程：按规则计算商店购物应收款额，遇负数输入提示重输

以下是使用 Python 语言实现的代码： ```python while True: purchase_amount = float(input("请输入购物额: ")) if purchase_amount < 0: print("输入有误，请重新输入！") continue if purchase_amount >= 1000: payable_amount = purchase_amount * 0.85 elif purchase_amount >= 500: payable_amount = purchase_amount * 0.9 elif purchase_amount >= 200: payable_amount = purchase_amount * 0.95 elif purchase_amount >= 100: payable_amount = purchase_amount * 0.97 else: payable_amount = purchase_amount print("应收款额为:", payable_amount) ``` 这段代码会不断要求用户输入购物额，然后根据优惠规则计算应收款额并输出。如果输入的购物额为负数，会提示重新输入。 ######[AI写代码神器 | 211点数解答 | 2024-09-26 15:08:35]
