+        next_assignment = {}


Suggested change

next_assignment = {}

next_assignment = None

Maybe we will declare it with None and return also return None if no future assignment?

+        next_assignment = {}
+        past_assignment = []


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.

Suggested change

sorted_assignments = sorted(assignments, key=lambda x: x.date)

create this variable and move it above the past assignments

Do we need this micro-optimization here if there is still only one cycle?
