Build a Medical Data Validator - Step 23

Python

Tell us what’s happening:

I’m stuck on Step 23.

My function creates the constraints dictionary and assigns:
def find_invalid_records(patient_id, age, gender, diagnosis, medications, last_visit_id):
constraints = {

}
constraints['patient_id'] = isinstance(patient_id, str)
return constraints

However, the test still fails with the message:

Your constraints dictionary should have a key patient_id with the value of isinstance(patient_id, str).

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',
    }
]

Welcome to the forum @mauriciopgsantos !

In this step, you already have a constraints dictionary available to write key-value pairs into. Look at your dictionary objects in medical_records and pattern your key-value syntax off of one of those.

Thanks my friend!
You solved for me
