Choose a project: a program that keeps the scores of a quiz game and shows who is winning. Write the first four steps of the method: the goal, the jobs, the data, and a small example with the expected answers worked out by hand.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Plan. Follow the first four steps of the eight.
- Goal. A program that keeps the scores of the players of a quiz and shows who is winning.
- Jobs.
add_points(scores, name, points): add points to a player (a new player starts at 0),leader(scores): the name of the player with the most points,ranking(scores): the players from the most points to the least.
- Data. A dictionary of name and score, because we look up and update by name. The ranking uses a list of tuples (name, score), made by
sorted. - A small example, worked out by hand. Start with an empty dictionary.
- Asha gets 10, Ravi gets 5, Asha gets 5, Meera gets 12.
- The scores are Asha 15, Ravi 5, Meera 12.
- The leader is Asha (15).
- The ranking is Asha 15, Meera 12, Ravi 5.
- The edges to test later: no players (no leader), a tie for the lead, a player with 0 points.
Check. Each job could be a function, and the example is the answer key.
Answer: The plan above.
