Rock-Paper-Scissors (Python). Stage 4/5

Scoring the game

Report a typo

Description

People love to see their results as they're advancing to their goals. So, let's learn how to show the scoreboard!

When the game starts, users must be able to enter their names. After that, the program should greet users and read a file named rating.txt.

In order to execute the test program correctly, name the file rating.txt and save it in the current directory, without subdirectories. In tests this file will be created, pre-filled with data. Make sure that you read the data correctly when you start the game.

It is the file that contains the current scores for different players. You can see the file format below: lines containing usernames and their scores, divided by a single space:

Tim 350
Jane 200
Alex 400

Take the current user score from the file and use it as a basis for counting the score during the game. For example, if a user entered Tim, then their score at the start of the game is 350. If a user inputs a name that is not on the list, the program should count the score from 0.

No need to write anything to the rating.txt file.

Print the user score with the !rating command. For example, if your rating is 0, then the program should print:

Your rating: 0

Add 50 points for every draw, 100 for every win, and 0 for losing.

Objectives

Your program should:

  • Output a line Enter your name: . Users enter their names on the same line (not the one following the output!);

  • Read input with the name and output a new line: Hello, <name>

  • Read rating.txt and check whether it contains an entry with the current username. If yes, use the score specified in the file as a starting point. If not, start the score from 0.

  • Play the game by the rules defined in the previous stages and read the user input;

  • If the input is !exit, output Bye! and stop the game;

  • If the input is the name of the option, then pick a random option and output a line with the result in the following format (<option> is the name of the option chosen by the program):

    • Loss: Sorry, but the computer chose <option>

    • Draw: There is a draw (<option>)

    • Win: Well done. The computer chose <option> and failed

  • For each draw, add 50 points to the score. For each win, add 100 points. In case a user loses, don't change the score;

  • If the input corresponds to anything else, output Invalid input;

  • Restart the game.

Examples

The greater-than symbol followed by a space (> ) represents the user input. Note that it's not part of the input.

Example 1:

Enter your name: > Tim
Hello, Tim
> !rating
Your rating: 350
> rock
Sorry, but the computer chose paper
> paper
Well done. The computer chose rock and failed
> scissors
There is a draw (scissors)
> !rating
Your rating: 500
> !exit
Bye!

Example 2:

Enter your name: > Chuck
Hello, Chuck
> scissors
There is a draw (scissors)
> rock
Well done. The computer chose scissors and failed
> paper
Well done. The computer chose rock and failed
> !rating
Your rating: 250
> !exit
Bye!
