Project: Community Sports Club Management System

Objective

Design a system to manage a sports club, involving members, coaches, and staff. This task focuses on using inheritance, composition, and object interaction while demonstrating relationships and behaviours unique to each class.

---

Step 1: Define the Base Class

1. Person Class

A base class for all individuals in the sports club.

Attributes:

• name: Full name of the person.
• age: The age of the person.
• contact_number: The person's contact number.

Methods:

• set_details(name, age, contact_number): Sets the person's details.
• get_details(): Returns a string summarising the person's details:
  "Name: [name], Age: [age], Contact Number: [contact_number]".

---

Step 2: Define Subclasses

2. Member Class (inherits from Person)

A class representing club members who participate in sports activities.

Attributes:

• Inherits all attributes from Person.
• membership_id: A unique ID for the member (e.g., "M3456").
• sport: The sport they are enrolled in (e.g., "Football").
• performance_scores: A list of scores reflecting their performance.

Methods:

• set_member_details(membership_id, sport): Sets the member's ID and sport.
• add_performance_score(score): Adds a score to the member’s performance_scores.
• calculate_average_score(): Calculates and returns the average score if there are scores; otherwise, returns 0.
• get_member_summary(): Returns the member’s details, including their average performance score.

---

3. Coach Class (inherits from Person)

A class representing the coaches who train members.

Attributes:

• Inherits all attributes from Person.
• coach_id: A unique ID for the coach (e.g., "C1234").
• specialisation: The sport they coach (e.g., "Tennis").
• salary: The coach's salary.
• mentees: A list of Member objects representing their mentees (starts as an empty list).

Methods:

• set_coach_details(coach_id, specialisation, salary): Sets the coach’s details.
• assign_mentee(member): Accepts a Member object, adds them to the mentees list, and prints:
  "Coach [coach_name] is now mentoring [member_name] in [member_sport]."
• get_mentees(): Returns a list of names and sports of all the coach’s mentees.
• increase_salary(percentage): Increases the coach’s salary by a given percentage.

---

4. Staff Class (inherits from Person)

A class representing administrative staff who manage the club.

Attributes:

• Inherits all attributes from Person.
• staff_id: A unique ID for the staff member (e.g., "S4567").
• position: Their job role (e.g., "Club Secretary").
• years_of_service: The number of years they have worked at the club.

Methods:

• set_staff_details(staff_id, position, years_of_service): Sets the staff member’s details.
• increment_years_of_service(): Increases the years_of_service by 1.
• assist_member(member): Accepts a Member object and prints:
  "Staff [staff_name] assisted [member_name] in resolving an issue."
• get_staff_summary(): Returns the staff member’s details, including years of service.

---

Step 3: Create and Use the Classes

1. Create Objects

   • Create 2 Member objects.
   • Create 2 Coach objects.
   • Create 1 Staff object.

2. Demonstrate Functionality

   • Assign a member to a coach using assign_mentee.
   • Add performance scores for a member and calculate their average score.
   • Use a staff member to assist a member.
   • Increase a coach's salary by 15%.
   • Increment a staff member’s years of service.

3. Output

   • Print the summaries for all objects, showing their updated details.

---

Extension Task (Harder)

Scenario: Develop a mentorship programme for coaches.

1. Add a mentorship_group attribute to the Coach class, which is a list of Coach objects that they are mentoring (starts as an empty list).

2. Add a mentor_coach(coach) method in the Coach class that:

   • Accepts another Coach object and adds them to the mentorship_group.
   • Prints:
     "Coach [coach_name] is now mentoring Coach [mentee_coach_name] in [mentee_specialisation]."

3. Add a get_mentorship_group() method in the Coach class that:

   • Returns a list of names and specialisations of the coaches in the mentorship_group.

Challenge: Make coaches simultaneously mentor members and other coaches while maintaining clear relationships.

Example Output:

coach1.mentor_coach(coach2)
coach1.assign_mentee(member1)

# Output
# Coach Alex is now mentoring Coach Beth in Football.
# Coach Alex is now mentoring Member John in Football.

coach1.get_mentorship_group()  # Returns: ["Beth (Football)"]
coach1.get_mentees()  # Returns: ["John (Football)"]
