🐍 #100DaysOfCode — Day 12: Scope & Number Guessing Game

Today I learned about scope in Python and built a fun Number Guessing Game as the project.

📝 Scope in Python

Python variables have different lifetimes depending on where they are declared.

• Local Scope → Exists only inside functions.

def drink_potion():
    potion_strength = 2
    print(potion_strength)  # works

drink_potion()
print(potion_strength)  # error, not defined outside

• Global Scope → Accessible everywhere.

player_health = 10

def drink_potion():
    print(player_health)  # works fine

• No Block Scope → Variables in loops/ifs still exist outside.

game_level = 3
if game_level < 5:
    new_enemy = "Skeleton"

print(new_enemy)  # still accessible

• Modifying Global Variables → Use global keyword.

enemies = 1

def increase_enemies():
    global enemies
    enemies += 1

• Global Constants → Written in ALL CAPS.

PI = 3.14159

🎮 Final Project: Number Guessing Game

I built a game where the computer picks a number between 1 and 100, and the player must guess it within limited attempts depending on difficulty.

import random

print("Welcome to the Number Guessing Game!")
print("I'm thinking of a number between 1 and 100.")
difficulty = input("Choose 'easy' or 'hard': ")
random_number = random.randint(1, 100)
def guess_check(level):
    attempts = 10 if level == "easy" else 5
    while attempts > 0:
        print(f"You have {attempts} attempts remaining.")
        guess = int(input("Make a guess: "))
        if guess > random_number:
            print("Too high.")
        elif guess < random_number:
            print("Too low.")
        else:
            print(f"You got it! The number was {random_number} 🎉")
            return
        attempts -= 1
    print("You've run out of guesses. You lose 😢")
guess_check(difficulty)

✅ Concepts Learned:

• Local vs Global scope
• Constants in Python
• Modifying global variables
• Implementing game logic with loops & conditionals

🚀 End of Day 12 — Onto Day 13!
