Suggested change
past_assignment = []
past_assignments = [assignment for assignment in sorted_assignments if assignment.date < datetime.now(timezone)]

If we iterate over the same list twice the complexity will be O(2N) that is by O-notation roughly the same as a single iteration.

What benefits will this give us, since this way we will iterate by sorted_assignments 2 times? In addition, we will also worsen the readability, as for me.
