1.獲取前一個星期的時間列表

def dateRange(beginDate):
    """
    設計時間格式，也就是取出今天前七天的時間列表
    :param beginDate:
    :return:
    """
    yes_time = beginDate + datetime.timedelta(days=+1)
    aWeekDelta = datetime.timedelta(weeks=1)
    aWeekAgo = yes_time - aWeekDelta
    dates = []
    i = 0
    begin = aWeekAgo.strftime("%Y-%m-%d")
    dt = datetime.datetime.strptime(begin, "%Y-%m-%d")
    date = begin[:]
    while i < 7:
        dates.append(date)
        dt = dt + datetime.timedelta(1)
        date = dt.strftime("%Y-%m-%d")
        i += 1
    return dates

2.獲取當前時間前一個月的時間列表

def get_date_list(begin_date, end_date):
    """
    獲取一個月的時間列表
    :param begin_date:
    :param end_date:
    :return:
    """
    dates = []
    dt = datetime.datetime.strptime(begin_date, "%Y-%m-%d")
    date = begin_date[:]
    while date <= end_date:
        dates.append(date)
        dt += datetime.timedelta(days=1)
        date = dt.strftime("%Y-%m-%d")
    return dates
