π What Are Loops in Programming?
Loops are a powerful concept in programming that let you repeat a block of code multiple times. Instead of writing the same code over and over, you create a loop that does the job for you.
Think of a loop like a washing machine cycle: you press start once, and it runs through all the steps until it's done — automatically.
πΉ Why Use Loops?
- ✅ Avoid repeating code manually
- ✅ Automate repetitive tasks
- ✅ Process large amounts of data easily
- ✅ Make your code cleaner and more efficient
πΉ Types of Loops
1. for
Loops
For loops run a set number of times. Perfect when you know how many times to repeat something.
for i in range(5):
print("Hello")
Output:
Hello
Hello
Hello
Hello
Hello
2. while
Loops
While loops repeat code as long as a condition is true. Useful when you don’t know exactly how many times to loop.
count = 0
while count < 3:
print("Counting", count)
count += 1
Output:
Counting 0
Counting 1
Counting 2
π Real-World Analogy
Imagine you’re baking cookies:
- πͺ For loop: You bake 12 cookies. Each cookie goes through the same steps.
- π§Ό While loop: You clean dishes until the sink is empty.
⚠️ Common Mistake: Infinite Loops
If your while
loop never becomes false, it keeps running forever. This is called an infinite loop.
while True:
print("This never stops!")
✅ Always make sure your loop has a condition that eventually becomes false.
π‘ Mini Challenge: Try It Yourself
Can you write a loop that prints all numbers from 1 to 10?
Here’s a hint:
for i in range(1, 11):
print(i)
Test it on your code editor or Python IDE!
π§ Summary
Loops are essential tools in any coder’s toolkit. Whether it's a for
loop that runs a specific number of times or a while
loop that waits for a condition — mastering them is a must.
Now that you’ve seen how they work, start experimenting with small loop exercises and see how much cleaner your code becomes.
π¬ Your Turn
π Have you written your first loop yet? What’s one repetitive task you'd automate with code?
