1.获取所有天，返回一个列表:

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

3.获取所有季度，返回一个列表:

def getBetweenMonth(begin_date):
        date_list = []
        begin_date = datetime.datetime.strptime(begin_date, "%Y-%m-%d")
        end_date = datetime.datetime.strptime(time.strftime('%Y-%m-%d', time.localtime(time.time())), "%Y-%m-%d")
        while begin_date <= end_date:
            date_str = begin_date.strftime("%Y-%m")
            date_list.append(date_str)
            begin_date = add_months(begin_date,1)
        return date_list
    
    def add_months(dt,months):
        month = dt.month - 1 + months
        year = dt.year + month / 12
        month = month % 12 + 1
        day = min(dt.day, calendar.monthrange(year, month)[1])
        return dt.replace(year=year, month=month, day=day)
    
    def getBetweenQuarter(begin_date):
        quarter_list = []
        month_list = getBetweenMonth(begin_date)
        for value in month_list:
            tempvalue = value.split("-")
            if tempvalue[1] in ['01','02','03']:
                quarter_list.append(tempvalue[0] + "Q1")

                quarter_list.append(tempvalue[0] + "Q3")
            elif tempvalue[1] in ['10', '11', '12']:
                quarter_list.append(tempvalue[0] + "Q4")
        quarter_set = set(quarter_list)
        quarter_list = list(quarter_set)
        quarter_list.sort()
        return quarter_list
