Convert two lists into a dictionary in Python?

Question

Imagine that you have: keys = ['name', 'age', 'food'] values = ['Monty', 42, 'spam']What is the simplest way to produce the following dictionary? a_dict = {'name' : 'Monty', 'age' : 42, 'food' : 'spam'}

Answer 1

Maybe another tutor will come along and find something simpler, but I'd just solve this with comprehension.

Assuming keys and values are the same size:

a_dict = {keys[i]: value for i, value in enumerate(values)}

by using enumerate, we preserve both and index, and a value. We use the index to retrieve the key, and keep the value as the value of that key.
