About Lesson

๐ŸŽฏ Learning Objectives

By the end of this lesson, learners will be able to:

  • Understand the need for loops in programming

  • Use for and while loops to repeat actions

  • Apply range() in loops

  • Control repetition based on conditions

๐Ÿ”น Why Use Loops?

Loops allow you to repeat a block of code multiple times, saving time and avoiding repetition.

Instead of writing:

python
print("Hello")
print("Hello")
print("Hello")

You can write:

python
for i in range(3):
print("Hello")

๐Ÿ”ธ The for Loop

The for loop is used to iterate over a sequence (like a list, string, or range of numbers).

Syntax:

python
for variable in sequence:
# code block

โœ… Example with range():

python
for i in range(1, 6):
print(i)

Output:

ย 
1
2
3
4
5

range(start, stop) generates numbers from start to stop - 1


๐Ÿ”ธ The while Loop

A while loop runs as long as a condition is True.

Syntax:

python
while condition:
# code block

โœ… Example:

python
count = 1
while count <= 5:
print("Count is:", count)
count += 1

โš ๏ธ Be Careful: Infinite Loops!

python
while True:
print("This will run forever")

โ— Make sure your loop has a condition that becomes False, or use break to stop it.


๐Ÿ”„ Loop Use Cases

Loop Type Best Used When
for You know how many times to repeat
while You want to loop until a condition is met

๐Ÿง  Mini Exercise

python
# Print even numbers from 2 to 10 using for loop
for num in range(2, 11, 2):
print(num)

# Sum numbers from 1 to 5 using while loop
total = 0
i = 1
while i <= 5:
total += i
i += 1
print("Total:", total)


๐Ÿ“ Assignment

Create a program using:

  • A for loop to print numbers 1 to 10

  • A while loop to print numbers from 10 down to 1
