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
