179. Python Program to Save and Load a Score List

Overview

Put the whole chapter together: write a file, read it back, and turn its text into real data.

Problem Statement

Read a whole number n, then n lines, each a name and a score separated by a comma, like Sunny,80. There may be spaces around the name or the score: strip them.

1. Save the scores in a file called scores.txt, one name,score line each, using with open(...).
2. Load them back from scores.txt: split each line at the comma and turn the score into a number.
3. Using the loaded scores, print each player as name: score, then the best player as Best: name (score), then the average with two decimals as Average: 82.33.

If two players share the best score, the one who came first is the best. n is always at least 1.

Write a function to save and a function to load. For example: save_scores(filename, records) and load_scores(filename), where each record is a (name, score) tuple.

Your program runs in the browser, so the file lives only in this tab's memory. Create it with "w" before you read it.

Use input() with no prompt text: the tests type the input for you, and a prompt would end up in your output.

Input

The number of players, then one name,score per line. Example:

3
Sunny,80
Rocky,95
Lucky,72

Output

The output for that example:

Sunny: 80
Rocky: 95
Lucky: 72
Best: Rocky (95)
Average: 82.33

The tests try 4 different inputs, including one player and a tie for the best score.
