Project 3 - Youth Baseball

For this project, you need to write a program that registers players for baseball teams in a youth league. There are two teams:

  • Bigs — players over 10 years old
  • Littles — players 10 years and younger

The program should allow you to enter all the players and their ages, then print out a report on the two teams.


The registration program needs two things to register a player:

  • name
  • age

The program should automatically assign players to the two teams based on their age.


For each team, the program prints:

  • Total members
  • Average age (rounded to zero decimal places)
  • Youngest age
  • Oldest age
  • Members (in a bulleted list)

Sample Code

You can find sample code in


  1. You should test your program on your own before you run the tests we provide.

  2. When you are ready to submit, use Gradescope. The grader has been setup to award partial credit. The points awarded are shown below. In addition, each section has partial credit. For example, if you are missing only a space in your output, you will get most of the credit.

Manual Grading

Refer to the Quality Code guide page for detailed explanations and examples on each of these rubric criteria.

Intent The intent of this project is for you to write generic functions to process lists of tuples.

Avoid creating multiple functions that perform the same task. Instead, aim to have a single, generic function that can handle similar operations. For example, do not create two functions find_bigs_oldest(bigs) and find_littles_oldest(littles) that find the oldest team member of a list. Instead, create one generic function find_oldest(team). This will avoid duplicate code.
