How to get two all dates (and other method summaries for processing datetime) in any time period

(1) Use the method to obtain all the dates in two any time period, the code is as follows:

#1. Convert a string to a datetime typedefStrtodatetime (datestr,format):returndatetime.datetime.strptime (Datestr,format)#2. Time converted to string, formatted as 2008-08-02defdatetostr (date):returnSTR (date) [0:10]#3, two days apart, for example: 2008-10-03 and 2008-10-01 are two days apartdefDateDiff (begindate,enddate): Format="%y/%m/%d"; BD=Strtodatetime (Begindate,format) Ed=strtodatetime (enddate,format) oneday=datetime.timedelta (Days=1) Count=0 whilebd!=ed:ed=ed-oneday Count+=1returnCount#4. Get all time of two time period, return listdefgetDays (begindate,enddate): Format="%y/%m/%d"Ed=strtodatetime (enddate,format) oneday=datetime.timedelta (Days=1) Num=datediff (begindate,enddate) +1Li=[]     forIinchRange (0,num): Li.append (Datetostr (ed)) Ed=ed-onedayreturnLi

(2) Set the start and end date (January 1, 2000 as of today 's date), the code is as follows:

def get_today ():    time.localtime (Time.time ())    = Time.strftime ('%y-%m-%d' , Time.localtime (Time.time ()))     return Tdate

(3) Run the following code in the main function to get all dates from January 1, 2000 to today.

def main ():p rint getDays (' 2000-01-01 ', Get_today ()) If __name__ = = ' __main__ ':    Main ()

In addition, there are a few other date-time processing summary of the small method, for informational purposes only. (from:http://www.linux-field.com/archives/360)
