How to Convert Different Date Formats to a Single Date format – Python

In this article, we gonna show how to convert different input Date formats to a single output date format.

Given Date Formats :

Case 1 : “2019-3-6”
Case 2: “Wed, 6, March, 19”
Case 3: “Wednesday, 6, March, 9”
Case 4: “6-3-2019” 

Output date format should be: 3/6/2019

// Importing datetime
 import datetime 
 
// First type of Date and it's format
 inputDate0 = "2019-3-6"
 DateFormat0 = "%Y-%m-%d"
 
 // Second type of Date and it's format
 inputDate1 = "Wed, 6, March, 19"
 DateFormat1 = "%a, %d, %B, %y"
 
 // Third type of Date and it's format
 inputDate2 = "Wednesday, 6, March, 19"
 DateFormat2 = "%A, %d, %B, %y"

 // Fourth type of Date and it's format
 inputDate3 = ""6-3-2019""
 DateFormat3 = "%d-%m-%Y"
 
 // Out date format
 outPutDateFormat = "%m/%d/%y"
 
 // Converting input date to Date type object
 date0 = datetime.datetime.strptime(inputDate0 , DateFormat0 )
 date1 = datetime.datetime.strptime(inputDate1 , DateFormat1 )
 date2 = datetime.datetime.strptime(inputDate2 , DateFormat2 )
 date3 = datetime.datetime.strptime(inputDate3 , DateFormat3 )
 
 // Print different combination of dates as per output format
 print datetime.date.strftime(date0, outPutDateFormat )
 print datetime.date.strftime(date1, outPutDateFormat )
 print datetime.date.strftime(date2, outPutDateFormat )
 print datetime.date.strftime(date3, outPutDateFormat )

Output will be like this

6/3/2019
6/3/2019
6/3/2019
6/3/2019
