Understanding Python Loops: A Beginner’s Guide

Loops are fundamental constructs in Python that allow you to execute a block of code multiple times. They are essential for automating repetitive tasks and handling collections of data efficiently. In this guide, we will cover the basics of loops in Python, including the for loop and the while loop, along with some practical examples.

Why Use Loops?

• Automation: Automate repetitive tasks to save time and effort.
• Efficiency: Process collections of data (like lists or dictionaries) efficiently.
• Control: Implement complex logic that requires repetitive execution of code blocks.

Types of Loops in Python

Python provides two primary types of loops:

1. For Loop
2. While Loop

For Loop

The for loop is used to iterate over a sequence (such as a list, tuple, dictionary, set, or string). It repeats the block of code for each item in the sequence.

Syntax:

for item in sequence:
    # Code block to execute

Example:

fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
    print(fruit)
