Tell us what’s happening:

I thought the syntax was correct, but the systems tells I should have p\d. That is what I have, right?

Your code so far

import re

I do not get it but I am also not familiar with the \d syntax. What is wrong in that syntax?

I solved it, got further.

4

you have lost one argument here, the string to test

reset the step, do not remove the second argument
