check if the string contains the desired Character position python

Question

I am using tesseract to extract Information for a driving licence. So i want to check if the extracted Information is correct. For example when i want to get the date of birth, it should be like this: 15.08.1999 ==> 2 int. 2 int. 4 int How can i do this? the second question is: sometimes the extracted info contains no points. I mean like this: 15 08 1999 So how can i check if there is a point in the second position of the string and if not put a point. Could someone help with this? Thanks

Answer 1

Use a regular expression that extracts the components of the date in either format.

import re

match = re.match(r'(\d{2})[. ](\d{2})[. ](\d{4})$', birthdate)
if match:
    day, month, year = match.groups()

[. ] [. ] will match either a . or space.
