Unit 2 Session 2 (Click for link to problem statements)

Understand what the interviewer is asking for by using test cases and questions about the problem.

• Will the points always be a positive integer?
  • Yes, but most solutions will work for negative point values too.

Plan the solution with appropriate visualizations and pseudocode.

General Idea: If the player is already in the dict, add points to their score, otherwise, make a new entry in the dict for them.

1) Check if player is in the dict 2) If so, add points to that player's current score 3) Otherwise, map player -> points in the dict 4) Return the updated dict 

⚠️ Common Mistakes

• If you try to ADD to a score for someone who is NOT already in the dict, you'll get a KeyError.

def update_score(scores, player, points): if player in scores: scores[player] += points else: scores[player] = points return scores
