python时间段切割,将间隔天数分割成多个

import datetime

# last_start:开始时间 last_end:结束时间 frequency间隔天数
def split_time_ranges(last_start, last_end, frequency):
    start_date = datetime.datetime.strptime(last_start, "%Y-%m-%d")
    end_date = datetime.datetime.strptime(last_end, "%Y-%m-%d")

    middle_date = datetime.datetime.now()
    time_collection = []
    while True:
        date = {}
        middle_date = start_date + datetime.timedelta(days=frequency)
        # 结束时间
        if middle_date > end_date:
            date["start"] = start_date
            date["end"] = end_date
            time_collection.append(date)
            break
        else:
            date["start"] = start_date
            date["end"] = middle_date
            time_collection.append(date)
            start_date = middle_date + datetime.timedelta(days=1)
    return time_collection


if __name__ == '__main__':
    aa = split_time_ranges("2022-05-01", "2022-05-31", 6)
    print(aa)

执行结果
