  It's easy. The first bit: [person tells you that you're getting a list of persons. That's the most important part. The rest is telling you how they're getting in that list. It's almost like a select query in (pseudo) SQL. select person from people where person.isvalid = true vs [person for person in people if person.isvalid]
