Tell us what’s happening:

hello everyone, i was going throught this beautiful workshorp i an got stuck at this level when throught all pass code but never got the solution please i will appreciate help

Your code so far

import re

for key in invalid_records:

        print(

            f"Unexpected format '{key}: {dictionary\[key\]}' at position {index}."

        )

        is_invalid = True

”please at this point where should i put the dot because i just tried but no result”

5

for key in invalid_records :

        val = dictionary\[key\]

        print(f"Unexpected format '{key}: {val}' at position {index}.")

        is_invalid = True

”please at this point where should i put the dot because i just tried but no result. i event tried updating my code but not still passing”

reset the step, something got changed elsewhere, then add the same code again, it should work
