Introduction to Iteration

Meaning of iteration: Repeating a set of instructions until a condition is met.

​

Importance in programming

Example from real life: Walking until reaching home

Types of Iteration in Python

• Entry controlled loops: for, while
• Infinite loops (unintended if condition never fails)

​

The while Loop

Syntax:

initialization

while (condition):

statements

increment or decrement

​

Loop continues until condition becomes false

Example of while Loop

count = 1

while count <= 5:

print("Hello")

count += 1

​

​

​

​

Output:

Hello

Hello

Hello

Hello

Hello

​

The for Loop : Used for definite iteration.

​

Syntax:

for variable in sequence:

statements

Example of for Loop

for i in range(1, 6):

print(i)

​

​

Output:

1

2

3

4

5

Control Statements

​

break → exit loop immediately

continue → skip current iteration, go to next

Summary :

​

Iteration avoids repetition of code.

​

Python provides while and for loops.

​

Control statements (break, continue) enhance loop control
