Dec 27, 2023 · Python While Loop is used to execute a block of statements repeatedly until a given condition is satisfied. When the condition becomes false, the line immediately after the loop in the program is executed. Syntax of while loop in Python. while expression: statement(s) Flowchart of Python While Loop.
Python has two primitive loop commands: while loops. for loops. The while Loop. With the while loop we can execute a set of statements as long as a condition is true. Example Get your own Python Server. Print i as long as i is less than 6: i = 1. while i < 6: print(i) i += 1. Try it Yourself »
In Python, we use the while loop to repeat a block of code until a certain condition is met. For example, number = 1 while number <= 3: print(number) number = number + 1. Run Code. Output. 1. 2. 3. In the above example, we have used a while loop to print the numbers from 1 to 3. The loop runs as long as the condition number <= 3 is satisfied.

In this tutorial, you'll learn about indefinite iteration using the Python while loop. You’ll be able to construct basic and complex while loops, interrupt loop execution with break and continue, use the else clause with a while loop, and deal with infinite loops.
A while loop repeats code until the condition is met. Unlike for loops, the number of iterations in it may be unknown. A while loop always consists of a condition and a block of code. A while loop ends if and only if the condition is true, in contrast to a for loop that always has a finite countable number of steps.
Python uses the while and for keywords to constitute a conditional loop, by which repeated execution of a block of statements is done until the specified boolean expression is true. The following is the while loop syntax. Syntax: while [boolean expression]: statement1. statement2. ... statementN.
Aug 18, 2023 · This article explains a while loop in Python. Unlike a for loop, which sequentially processes iterable elements such as a list, a while loop repeats as long as its condition evaluates to True. 8. Comp ...
The while statement checks the condition at the beginning of each iteration. It’ll execute the body as long as the condition is True. In the body of the loop, you need to do something to stop the loop at some time. Otherwise, you’ll get an indefinite loop that will run forever until you close the application.
Learn how to use Python's while loop to execute a block of code repeatedly until a certain condition is met. This tutorial includes examples of while loop syntax, characteristics, and manipulation techniques such as the break and continue statements.
