In this post, we're gonna learn how to write the different types of loops in Python for beginners.

loops in python

What're Loops?

  • Loops mean repetition, looping back over the same block of code again and again.
  • A loop statement allows us to execute a statement or group of statements multiple times.
  • Loops can execute a block of code as long as a specified condition is reached.

Loops in Python

Python has two primitive loop commands:

  • While loop: Loops through a block of code as long as a specified condition is True.
  • For loop: When you know exactly how many times you want to loop through a block of code.

While Loop in Python

  •  A while loop in Python repeatedly executes a target statement as long as a given condition is true.

For loop in Python

  • A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string).

The Syntax of For loop in Python

for iterating_var in sequence:

For loop in Python\

You can also loop through the letters in the word:

for x in "apple":

for loop with range function

syntax of range function:

range(start, stop [, step])

use: it usually used in for statement to define the number of loops iteration or

for i in range(1, 4):
    print ('This is the', i, 'iteration.')


This is the 1 iteration.
This is the 2 iteration. 
This is the 3 iteration.

the default step value is 1

Example of defining the step by 2

this example will print the odd numbers of iteration

for i in range(1, 9, 2):
    print ('This is the', i,' iteration.')


This is the 1 iteration.
This is the 3 iteration.
This is the 5 iteration.
This is the 7 iteration.


In this post, we have discussed the different types of loop in Python, and when we can use it.
