python - How do I convert two lists into a dictionary?

Question

Imagine that you have the following list.

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

Like this:

keys = ['a', 'b', 'c']
values = [1, 2, 3]
dictionary = dict(zip(keys, values))
print(dictionary) # {'a': 1, 'b': 2, 'c': 3}

Voila :-) The pairwise dict constructor and zip function are awesomely useful.
