Beginner's Tutorial on for Loop in Python

Introduction

In Python, a for loop is a control flow statement. It allows you to execute a block of code multiple times. It is used for iterating over a sequence (like a list, tuple, string, or dictionary) or other iterable objects.

Basic Syntax

for variable in iterable:  
    # code block to be executed

• variable will take each value from the iterable one by one.
• iterable is the sequence or iterable object you want to loop over.
• code block is the block of code that will be executed for each value in the iterable.

Examples

Example 1:Loop Over a List

fruits = ["apple", "banana", "cherry"] 

    for fruit in fruits:  
        print(fruit)

Output:

apple
banana
cherry

Example 2: Looping Over a Range

The range() function generates a sequence of numbers

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

Output:

0  
1  
2  
3  
4
