Build a Medical Data Validator - Step 18

Python
1

Tell us what’s happening:

Im stuck at the STEP 18 of the Medical Data Validator. I added the code as under
if set(dictionary.keys()) != key_set:
print(‘Invalid format: {dictionary} at position {index} has missing and/or invalid keys.’)
is_invalid=True
if is_invalid:
return False
The console says “Valid Format” but the code does not pass. The message
You should print “Invalid format: at position has missing and/or invalid keys.” appears. The code seems to be perfect …

Your code so far

medical_records = [
    {
        'patient_id': 'P1001',
        'age': 34,
        'gender': 'Female',
        'diagnosis': 'Hypertension',
        'medications': ['Lisinopril'],
        'last_visit_id': 'V2301',
    },
    {
        'patient_id': 'p1002',
        'age': 47,
        'gender': 'male',
        'diagnosis': 'Type 2 Diabetes',
        'medications': ['Metformin', 'Insulin'],
        'last_visit_id': 'v2302',
    },
    {
        'patient_id': 'P1003',
        'age': 29,
        'gender': 'female',
        'diagnosis': 'Asthma',
        'medications': ['Albuterol'],
        'last_visit_id': 'v2303',
    },
    {
        'patient_id': 'p1004',
        'age': 56,
        'gender': 'Male',
        'diagnosis': 'Chronic Back Pain',
        'medications': ['Ibuprofen', 'Physical Therapy'],
        'last_visit_id': 'V2304',
    }   
]


def validate(data):
    is_sequence = isinstance(data, (list, tuple))

    if not is_sequence:
        print('Invalid format: expected a list or tuple.')
        return False
        
    is_invalid = False
    key_set = set(
        ['patient_id', 'age', 'gender', 'diagnosis', 'medications', 'last_visit_id']
    )

    for index, dictionary in enumerate(data):
        if not isinstance(dictionary, dict):
            print(f'Invalid format: expected a dictionary at position {index}.')
            is_invalid = True


# User Editable Region

        if set(dictionary.keys()) != key_set:
            print('Invalid format: {dictionary} at position  {index} has missing and/or invalid keys.')    
            is_invalid=True 

# User Editable Region

        if  is_invalid:
            return False

    print('Valid format.')
    return True



validate(medical_records)
