🔁 Python Loops for Beginners

🔁 What are Loops?

Loops are used to execute a block of code repeatedly until a condition becomes false.

⭐ Why Use Loops?

• Reduce code repetition
• Save time and effort
• Make programs easier to manage
• Automate repeated tasks

🔢 Python for Loop

A for loop is used to iterate over a sequence like list, string, or range.

for i in range(5):
    print(i)

Output:

0
1
2
3
4

⏳ Python while Loop

A while loop runs as long as the condition is true.

count = 1

while count <= 5:
    print(count)
    count += 1

🔢 range() Function

The range() function generates a sequence of numbers.

for number in range(1,6):
    print(number)

🛑 break Statement

break is used to stop the loop immediately.

for i in range(10):

    if i == 5:
        break

    print(i)

⏭️ continue Statement

continue skips the current iteration and moves to the next one.

for i in range(5):

    if i == 2:
        continue

    print(i)

🔄 Nested Loops

A loop inside another loop is called a nested loop.

for i in range(3):

    for j in range(2):

        print(i,j)

🚀 Practice Examples

• Print numbers from 1 to 100.
• Create multiplication table using loops.
• Find the sum of numbers using a loop.
• Print patterns using nested loops.

❓ Frequently Asked Questions

1. How many types of loops are in Python?

Python mainly has two loops: for loop and while loop.

2. What is the use of range()?

range() creates a sequence of numbers for looping.

3. Can loops be nested in Python?

Yes, one loop can be placed inside another loop.
