Great job! Now let's help the customer service department send some emails.
The file named customers_data.json stores customer names and email addresses. But not everyone shared their email address – some are unknown.
Read the customers_data.json file. Create a new dictionary that only contains information on people who provided their email. Save the results to a file named customers_with_emails.json.
Note: Each customer in customers_data.json has four fields: id, first_name, last_name, and email. The email field will sometimes have a null value.
Remember, the variable will store information from the file:
emails = []
for customer in data:
if customer["email"] is not None:
emails.append(...)
