Exercise: Refactoring - Extract CSV Reading Into Function (csv.dictreader)

Requirement

Following Exercise: Read CSV File (csv.dictreader), refactor read-userdb-header.py to not directly output the user records as specified.

Rather, create a function that reads the CSV file, and returns a list of user records - dictionaries with specified keys - of the form,

{
    'id': 2,    # int
    'firstname': 'Jörg',
    'lastname': 'Faschingbauer',
    'birth': '19.6.1966',
}

That list is then used as follows in the main part of the program (the part that creates the output which remains the same):

user_records = read_csv_header(filename)
for rec in user_records:
    ... create output like before, no change ...
