本文实例讲述了Python实现计算两个时间之间相差天数的方法。分享给大家供大家参考,具体如下:

from datetime import date
import time
nowtime = date.today()
def convertstringtodate(stringtime):
 "把字符串类型转换为date类型"
 if stringtime[0:2] == "20":
 year=stringtime[0:4]
 month=stringtime[4:6]
 day=stringtime[6:8]
 begintime=date(int(year),int(month),int(day))
 return begintime
 else :
 year="20"+stringtime[0:2]
 month=stringtime[2:4]
 day=stringtime[4:6]
 begintime=date(int(year),int(month),int(day))
 return begintime
def comparetime(nowtime,stringtime):
 "比较两个时间,并返回两个日期之间相差的天数"
 if isinstance(nowtime,date):
 pass
 else:
 nowtime=convertstringtodate(nowtime)
 if isinstance(stringtime,date):
 pass
 else:
 stringtime=convertstringtodate(stringtime)
 result=nowtime-stringtime
 return result.days
"""

 endtime=nowtime
 result=endtime-begintime
 return result.days
 else :
 year="20"+stringtime[0:2]

print isinstance("20141012",date)
