如何在两个日期之间进行活动编号

import datetime

def generate_activity_number(start_date, end_date):
    current_date = start_date
    activity_number = 1
    activity_numbers = []

    while current_date <= end_date:
        # 根据规则生成活动编号
        activity_number_str = current_date.strftime("%Y%m%d") + str(activity_number).zfill(3)
        activity_numbers.append(activity_number_str)

        # 日期加1
        current_date += datetime.timedelta(days=1)

        # 活动编号加1
        activity_number += 1

    return activity_numbers

# 示例用法
start_date = datetime.date(2022, 1, 1)
end_date = datetime.date(2022, 1, 5)
numbers = generate_activity_number(start_date, end_date)
print(numbers)
