NUMBER GUESSING GAME

How I Built a Simple Leaderboard System (and Finally Understood Sorting Properly)
When I first heard "leaderboard system", I thought it would be complicated.
But after trying it myself, I realized it’s just about organizing data clearly.

Problem
I wanted to:
Store user performance
Show leaderboard
Sort based on difficulty and attempts

** Code (Python)**
Python
class Solution:
def leaderboardSystem(self):
leaderboard = [
{"name": "Asha", "score": 95, "difficulty": "Hard", "attempts": 2},
{"name": "Ravi", "score": 80, "difficulty": "Medium", "attempts": 3},
{"name": "John", "score": 70, "difficulty": "Easy", "attempts": 1},
{"name": "Meena", "score": 85, "difficulty": "Hard", "attempts": 4}
]

    difficulty_order = {
        "Easy": 1,
        "Medium": 2,
        "Hard": 3
    }

    sorted_data = sorted(
        leaderboard,
        key=lambda x: difficulty_order[x["difficulty"]]
    )

    print("\n🏆 Leaderboard\n")
    print("Name     Score   Difficulty   Attempts")
    print("--------------------------------------")

    for user in sorted_data:
        print(f'{user["name"]:<8} {user["score"]:<7} {user["difficulty"]:<11} {user["attempts"]}')
