Python得到两个时间段的每一天的列表

 date_list = []
    begin_date = datetime.datetime.strptime(begin_date, "%Y-%m-%d")
    end_date = datetime.datetime.strptime(end_date, "%Y-%m-%d")
    while begin_date <= end_date:
        date_str = begin_date.strftime("%m-%d")
        date_list.append(date_str)
        begin_date += datetime.timedelta(days=1)
    print date_list
