Build a Medical Data Validator - Step 44

Python
1

Tell us what’s happening:

I get the right output with this code, but I still get an error:

My output: Unexpected format gender: chicken at position 1

“You should print Unexpected format '<key>: <val>' at position <index>. (where <key>, <val>, and <index> should be replaced by the current key, value and index) inside your for loop.”

Is there a better way to do this?

Your code so far

import re
