Answer 1

Pythons datetime library might be helpful.

Please refer below code.

from datetime import datetime

datetime.datetime.strptime('29/01/21', '%d/%m/%y').strftime("%M/%d/%Y")

Answer 2

This is one solution:

mystring = '29/01/21'
mystring = mystring[:6]+'20'+mystring[-2:]
print(mystring)

Output:

'29/01/2021'
