Tell us what’s happening:

Does anybody know what’s missing?

    if not dictionary.keys() == key_set:
        print(f"Invalid format: {dictionary} at position {index} has missing and/or invalid keys.")
        is_invalid=True

Your code so far

medical_records = [

nothing is missing, the tests expect you to write this in a slightly different way. Which operator is equivalent to not (a == b) to check if a and b are not the same?
