Is it possible to block the possibility of entering literal data into the console, similar to Delphi?

Question

Python

Hello!
I wonder what the function is called when, when entering data into some window / console, the ability to enter letters was basically blocked? That is, for example, you can enter only numbers and only two-digit ones. I know that there is such a function in Delphi, but I forgot what it is called: I'm interested in having one in python.
Thank you!

If you mean the Delphi functions of the Character.IsLetter/IsNumber type, then Python has isalpha and so on.

you can filter on input.
