At the start of each run, the program picks a random integer between 1 and 100. Your goal is to guess it using the “too high” or “too low” feedback after each attempt. There is no guess limit — play continues until you find the number.

How to run

python3 Number_Guessing_Game.py

​
Gameplay

1

Start the game

Run the script. A random number between 1 and 100 is chosen immediately and kept secret.
2

Enter a guess

Type an integer at the prompt. The valid guessing range is strictly between 1 and 100 — the game rejects values of exactly 1 or 100 and anything outside that range with the message "Please enter a number between 1 and 100".
3

Read the feedback

  • If your guess is too high: Too high
  • If your guess is too low: Too low
  • If your guess matches: You win! and the game ends.

​
Terminal session example

Guess a number between 1 and 100: 50
Too low
Guess a number between 1 and 100: 75
Too high
Guess a number between 1 and 100: 62
Too low
Guess a number between 1 and 100: 68
Too high
Guess a number between 1 and 100: 65
You win!
Entering a non-numeric value (e.g., hello) prints "Value error!" but the game continues — you can keep guessing without restarting.

​
Tips for winning efficiently

The fastest strategy is a binary search: always guess the midpoint of the remaining range.
  1. Start with 50 (midpoint of 1–100).
  2. If “Too low”, your next guess is 75 (midpoint of 51–100).
  3. If “Too high”, your next guess is 25 (midpoint of 1–49).
  4. Keep halving the range after each clue.
This approach finds any number in at most 7 guesses, since log₂(100) ≈ 6.6.
