The Ultimate Guide to For Loop in Python: How to Use For Loop to Iterate through Sequences and Lists

 

A for loop in Python is used to repeat a block of code a specific number of times, or until a certain condition is met. It allows you to iterate over elements of a sequence (e.g. list, tuple, string, etc.) or other objects that support iteration. Discover the power of the Python for loop and how it can simplify your code. Learn how to use the for loop in Python to efficiently iterate over elements of a sequence or other objects. Get step-by-step examples and tips on how to make the most of the for loop in your Python programming.

# Iterate over a range of numbers

for i in range(10):

    print(i)

Output:-

1

2

3

4

5

6

7

8

9

This will output the numbers from 0 to 9. You can also use a for loop to iterate over the elements of a list:

# Iterate over the elements of a list

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

for fruit in fruits:

    print(fruit)

Output:-

apple

banana

cherry
