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

2.获取所有月，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)

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") elif tempvalue[1] in ['04','05','06']: quarter_list.append(tempvalue[0] + "Q2") elif tempvalue[1] in ['07', '08', '09']: 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
