It is unnecessary to use a comprehension just to loop over the iterable and create a list/set/dict out of it. Python has a specialized set of tools for this task: the list/set/dict constructors, which are faster and more readable.

Bad practice

states = [
    ('AL', 'Alabama'),
    ('AK', 'Alaska'),
    ('AZ', 'Arizona'),
    ('AR', 'Arkansas'),
    ('CA', 'California'),
    # ...
]

abbreviations_to_names = {
    abbreviation: name
    for abbreviation, name in states
}

Recommended

states = [
    ('AL', 'Alabama'),
    ('AK', 'Alaska'),
    ('AZ', 'Arizona'),
    ('AR', 'Arkansas'),
    ('CA', 'California'),
    # ...
]

abbreviations_to_names = dict(states)
