The majority of the world puts days in front of months in their dates:

However, there can be cases when you get as input a date where the month is in front of the day.

If you want to convert those dates in the format that the majority of the world uses, here is how:

 from datetime import datetime
 ​
 date = '04.27.2021'
 result = datetime.strptime(date, "%m.%d.%Y").strftime("%d.%m.%Y")
 ​
 print(result) # 27.04.2021

That’s basically it.

I hope you find this useful.
