Answer 1

I use this for working with csv files:

import csv


def open_csv(path):
'''return a list of dictionaries
'''
    with open(path, 'r') as file:
        reader = csv.DictReader(file)
        return [dict(row) for row in reader]

print(open_csv('./test.csv'))

Input csv:

first_name,last_name,email
John,Doe,john.doe@example.com
Jane,Doe,jane.doe@example.com
Foo,Bar,foo.bar@example.com

Output:

[{'first_name': 'John', 'last_name': 'Doe', 'email': 'john.doe@example.com'}, {'first_name': 'Jane', 'last_name': 'Doe', 'email': 'jane.doe@example.com'}, {'first_name': 'Foo', 'last_name': 'Bar', 'email': 'foo.bar@example.com'}]

I've learned to let the csv package handle format parsing on its own, its pretty awesome at that!
