This is true, but in code reviews and such, it often boils down to familiarity above anything else, like someone preferring

    names = []
    for record in records:
        names.append(record["name"])

to

    names = [record["name"] for record in records]

Now, I might say something if I saw this:

    import operator
    names = list(map(operator.itemgetter("name"), records))

Seems a bit unidiomatic given that list comprehensions are in the language... but probably many disagree.
