Part 4: Loops — Automating Repetition and Making Simple Games (with Help from AI)

Loops let your code do more with less — running the same block of code multiple times until a condition is met. In this part, we’ll explore:

• for loops and range()
• while loops and loop control
• A mini number guessing game
• How to use AI tools to generate custom loop challenges

---

🔁 Why Use Loops?

Loops are useful when you want to:

• Repeat an action multiple times
• Iterate through a list of items
• Keep asking for user input until a correct response is given

---

🔂 for Loops with range()

Use a for loop when you know how many times to repeat something.

for i in range(5):
    print("Looping:", i)

This prints:

Looping: 0
Looping: 1
Looping: 2
Looping: 3
Looping: 4

Note: range(5) starts at 0 and ends at 4 (not 5!).

---

🔄 while Loops

Use while loops when you want to repeat something until a condition is false.

count = 0

while count < 3:
    print("Counting:", count)
    count += 1

Be careful! while loops can go forever if the condition never becomes false.

---

⏹ Loop Control: break and continue

• break: exit the loop early
• continue: skip the current iteration and continue

for i in range(5):
    if i == 3:
        break
    print(i)

for i in range(5):
    if i == 2:
        continue
    print(i)

🎮 Mini Project: Number Guessing Game

Let’s make a simple game!

import random

secret = random.randint(1, 10)
guess = None

while guess != secret:
    guess = int(input("Guess a number between 1 and 10: "))
    
    if guess < secret:
        print("Too low!")
    elif guess > secret:
        print("Too high!")
    else:
        print("You got it!")

🧠 AI Tip: Use ChatGPT to Create Loop Challenges

Ask:

“Give me 5 Python loop challenges for beginners.”

ChatGPT can generate tasks like:

• Print the first 10 squares
• Loop through a string and count vowels
• Make a simple password checker

Want to level up? Ask:

“Can you turn that number guessing game into a two-player version?”

📚 Reinforcement Resources

• 🔗 Python Loops – W3Schools
• 🔗 Python Loop Examples – Programiz
• 🔗 Replit – Practice Loops
• 🤖 ChatGPT: Ask for explanations, generate variations, or simulate games

---

🎯 Practice Challenge

Create a loop that:

• Asks the user for a number between 1–10
• Keeps asking until the correct number is guessed
• Counts how many tries it took

Bonus: Ask ChatGPT to help you make the game “smarter” by giving hints.

🏁 Coming Up in Part 5…

Next up, we’ll cover lists, tuples, and dictionaries — three core Python data structures. You’ll learn how to store and manipulate collections of data, and use AI to simulate real-world data sets.

Hint: We’ll build a simple contact book using a dictionary!
