(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:
