Address: 2nd Floor, Kapil Vihar, Opp. Metro Pillar No.354, Pitampura, New Delhi, Delhi, 110034, IN
Telephone: +91-9667708830
Price range: ₹₹

Difficulty: Lv ★ | Prerequisites: Basic Weeks 4-5 (Conditionals, Loops, random)

Goal

User vs Computer Rock-Paper-Scissors — best of 3, with a cumulative overall record

Differences from Basic Assignment

Basic Week 4 = outputs the result once and ends
Here = best of 3 + infinite loop + re-request for wrong input + cumulative overall record

Requirements

Input: Rock, Paper, Scissors (full word or r/p/s)
The computer uses random.choice
Display the result every round (win/loss/draw, current score)
The first to reach 2 wins takes the match
After a match, ask "Play one more game?"
Accumulate the overall match record (wins/losses)

Input/Output Example

[Round 1]  Current Score (0 : 0)
Choose (Rock/Paper/Scissors or r/p/s): Scissors
Computer: Paper → User Wins!

[Round 2]  Current Score (1 : 0)
Choose (Rock/Paper/Scissors or r/p/s): Rock
Computer: Rock → Draw

...

🏆 Match Winner: User (2:1)

One more game? (y/n): n

[Overall Record]  User wins: 1, Computer wins: 0

Thanks for playing!

Challenge Task

The computer learns user patterns (predict the next move from the last 3 inputs)
Save the overall record to a file

Execution

python solution.py

Grading Checklist

Re-request wrong input
Best of 3 handled correctly
Accumulate the overall match record
Greet on exit
