error:string not recognized valid datetime on datetime.parseexact.

"dd/mm/yyyy" 

to

"m/d/yyyy" or "m/d/yyyy h:m:s tt" //the first 1 use .toshortdatestring(), second 1 1/21/2016 12:00:00 

the first 1 takes care case 21/12/1997

the second 1 takes care 12/21/1997, 2/21/1997, 12/2/1997, , 2/1/1997 in addition take care of time info
