本文实例为大家分享了python计算日期之间的放假日期，供大家参考，具体内容如下
代码如下：
#encoding=utf-8
print '中国'
#自动查询节日 给定起始日期和结束日期，自动获取总共的节假日天数
import datetime
from dateutil import rrule,easter
try: set
except NameError: from sets import Set as set
#复活节
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]
#开始到结束的节礼日列表
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]
#返回开始和结束日期之间的圣诞节列表
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]
#返回劳动节列表
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]
#读取设定的节假日
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 = h飞艇稳赚不赔的打法>
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')
打印结果如下：
中国
(4, [datetime.date(2014, 4, 20), datetime.date(2014, 12, 25), datetime.date(2014, 3, 23), datetime.date(2014, 9, 1)])
