根据时间进行降价的函数

您可以使用以下代码实现 “根据时间进行降价”的函数：

import datetime

def calculate_discounted_price(original_price, discount_percentage, discount_duration):
    current_time = datetime.datetime.now()
    end_time = current_time + datetime.timedelta(hours=discount_duration)
    while current_time < end_time:
        current_time = datetime.datetime.now()
        remaining_duration = (end_time - current_time).total_seconds() / 3600.0
        current_discount_percentage = (remaining_duration / discount_duration) * discount_percentage
        current_price = original_price * (1 - (current_discount_percentage / 100))
        print("Current discounted price: ", current_price)

    print("Discount period has ended. Original price: ", original_price)

# Example usage
calculate_discounted_price(100, 50, 2)

这个函数将接收三个参数：原价，折扣百分比和折扣持续时间（以小时为单位）。函数将逐渐降低折扣百分比，直到折扣持续时间结束。在此期间，函数将输出当前的折扣价格，一旦折扣时间结束，函数将打印原始价格。
