本文實例為大家分享了python計算日期之間的放假日期，供大家參考，具體內容如下

代碼如下：

#encoding=utf-8  print '中國'  #自動查詢節日 給定起始日期和結束日期，自動獲取總共的節假日天數  import datetime from dateutil import rrule,easter   try: set except NameError: from sets import Set as set  #復活節 def all_easter(start, end):   easters = [easter.easter(y) for y in xrange(start.year,end.year+1)]   return [d for d in easters if start<=d<=end]  #開始到結束的節禮日列表 def all_boxing(start, end):   one_day = datetime.timedelta(days=1)   boxings = [easter.easter(y) + one_day for y in xrange(start.year,end.year+1)]   return [d for d in boxings if start<=d<=end]   #返回開始和結束日期之間的圣誕節列表 def all_christmas(start, end):   christmases = [datetime.date(y,12,25) for y in xrange(start.year, end.year + 1)]   return [d for d in christmases if start<=d<=end]  #返回勞動節列表 def all_labor(start, end):   labors = rrule.rrule(rrule.YEARLY, bymonth=9, byweekday=rrule.MO(1),dtstart=start, until=end)   return [d.date() for d in labors]  #讀取設定的節假日 def read_holidays(start, end, holidays_file='holidays.txt'):   try:     holidays_file = open(holidays_file)   except IOError,err:     print 'open failed'     return []   holidays = []      for line in holidays_file:     if line.isspace() or line.startswith('#'):       continue     try:       y,m,d = [int(x.strip()) for x in line.split(',')]       date = datetime.date(y,m,d)     except ValueError:       print 'Invalid line find'       continue     if start <= date <=end:       holidays.append(date)         holidays_file.close()   return holidays         holidays_by_country = { 'US':(all_easter,all_christmas,all_labor), 'IT':(all_easter,all_boxing,all_labor) }  def holidays(cc,start,end,holidays_file='holidays.txt'):   all_holidays= read_holidays(start,end,holidays_file)   functions = holidays_by_country.get(cc,())   for function in functions:     all_holidays += function(start,end)   all_holidays = list(set(all_holidays))   return (len(all_holidays),all_holidays)  test_file = open(r'D:/123.txt','w') test_file.write('2014,3,23') test_file.close()  print holidays('US',datetime.date(2014,1,1),datetime.date(2014,12,31),r'D:/123.txt') 

打印結果如下：

中國
(4, [datetime.date(2014, 4, 20), datetime.date(2014, 12, 25), datetime.date(2014, 3, 23), datetime.date(2014, 9, 1)])
