Hi,
I am trying to figure out how to update a dictionary. Specifically, I am trying to figure out #19 in the medical insurance project (https://www.codecademy.com/paths/data-science/tracks/dscp-python-fundamentals/modules/dscp-python-dictionaries/projects/ds-python-dictionaries-project)

#19 wants you to write a function that will take the name and the person’s medical record into the medical records dictionary.

The medical records need to have the following form:

{'Marina': {'Age': 27, 'Sex': 'Female', 'BMI': 31.1, 'Children': 2, 'Smoker': 'Non-smoker', 'Insurance_cost': 6607.0}, 'Vinay': {'Age': 24, 'Sex': 'Male', 'BMI': 26.9, 'Children': 0, 'Smoker': 'Non-smoker', 'Insurance_cost': 3225.0}, ...}

I have tried writing the following but only received a syntax error but nothing else.

def update_medical_records(name, age, sex, bmi, children smoker, insurance_cost):
  medical_records_dict[name] = {"Age": age, "Sex": sex, "BMI": bmi, "Children": children, "Smoker": smoker, "Insurance_cost": insurance_cost}
  medical_records.update(medical_records_dict)

Any ideas why this function won’t work?

Thank you so much for helping!

@nojaa, welcome to the forums!

It looks like you’re missing a comma between children and smoker in your function. That is likely what is throwing the syntax error.

Oh my goodness, you are right! Thank you so much!!!

Furthermore, I noticed that I needed to add an empty dictionary first for it to work.

def update_medical_records(name, age, sex, bmi, children, smoker, insurance_cost):
  medical_records_dict = {}
  medical_records_dict[name] = {"Age": age, "Sex": sex, "BMI": bmi, "Children": children, "Smoker": smoker, "Insurance_cost": insurance_cost}
  medical_records.update(medical_records_dict)

For the final code in the link below I can’t get code to work and not sure why. It just says “SyntaxError: unexpected E0F while parsing”. Can someone please help. The code i’m talking about is the following:

for name, record in medical_records.items():

Thank you!

Check your parentheses in the final line of code.

Thank you. Found the issue. Working now.

I keep getting NameError when trying to run this function, any idea why?

Hi there.

It would be helpful if you also posted your code; you can find instructions on how to do that by clicking here.

NameError would suggest that you are attempting to use a variable which has not been declared yet.

Hi all,
concerning task #14, I was wondering if there’s a shorter way to add the medical records INSTEAD of writing all the following:

medical_records["Vinay"] = {"Age": 24, "Sex": "Male", "BMI": 26.9, "Children": 0, "Smoker": "Non-smoker", "Insurance_cost": 3225.0}

medical_records["Connie"] = {"Age": 43, "Sex": "Female", "BMI": 25.3, "Children": 3, "Smoker": "Non-smoker", "Insurance_cost": 8886.0}

medical_records["Isaac"] = {"Age": 35, "Sex": "Male", "BMI": 20.6, "Children": 4, "Smoker": "Smoker", "Insurance_cost": 16444.0}

medical_records["Valentina"] = {"Age": 52, "Sex": "Female", "BMI": 18.7, "Children": 1, "Smoker": "Non-smoker", "Insurance_cost": 6420.0}

Thanks in advance for your help

Hello,

I keep getting a syntax error for the 1st line, “def update_medical_records” utilizing your code.

Did you have this issue?

Thanks.

That would appear to be the precise issue that they were posting about, from reading the OP… :slight_smile:
