Python

Tell us what’s happening:

This code is failing the test for the final print statement, but I believe it’s correct. What am I missing?

if set(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 = [
    {
        'patient_id': 'P1001',

Welcome to the forum @dhorowitz001

Here is a comparison of the original code and your code.

The code in blue is the original code, the code in red is your code.
The code in magenta is the overlap.

It looks like you indented one of the if statements.

Try unindenting it.

Happy coding
