How do I check date of birth format is correct

Question

I'm currently coding an account signup on python and I need the user to enter their date of birth in the format DD/MM/YYYY.

How would I be able to check in the code if the input is valid or not?

dob=input("Enter your date of birth in the format DD/MM/YYYY")

Answer 1

import datetime

try:
    date_of_birth = datetime.datetime.strptime(dob, "%d/%m/%Y")
except:
    print("Incorrect date!")
