直接上code了

 

def get_wed_date():
    """
    This function obtains last Wednesday date
    """

    uni_string = lambda month,day: "".join([str(month), str(day)]) if len(day) > 1 else \
        "".join([str(month), "0", str(day)])

    logging.info("Start to calculate the last Wednesday date\n")
    today = datetime.date.today()
    logging.info("Today date: {0}\n".format(uni_string(str(today.month), str(today.day))))
    weekday = today.weekday()
    last_wed = today - datetime.timedelta(days=weekday + 5)
    last_last_wed = today - datetime.timedelta(days=weekday + 12)
    wed_list = [uni_string(str(last_wed.month), str(last_wed.day)), uni_string(str(last_last_wed.month), str(last_last_wed.day))]
    logging.info("Last Wednesday date: {0}\n".format(wed_list[0]))
    logging.info("Last Last Wednesday date: {0}\n".format(wed_list[1]))
    return wed_list

程序运行打印如下：
