Random draw for a competition.

Competitions often include a first round where teams are drawn against each other randomly.

Cup draw

⭐⭐⭐

Make

Write a program that allows the user to enter any number of team names. The computer shuffles the teams and then outputs all the team names two at a time. If there are an odd number of teams, the word “bye” is added to the list so that one team gets an automatic place in the second round. You only need to simulate the draw for round one.

Success Criteria

Remember to add a comment before a subprogram, selection or iteration statement to explain its purpose.

Complete the subprogram called input_teams that:

  1. Asks the user to input two teams.
  2. Appends the two teams to a list of teams.
  3. Asks the user if they want to enter two more teams.
  4. If the user inputs “y” the process of inputting and appending teams is repeated until the user inputs “n”.
