Python has two primitive loop commands: With the while loop we can execute a set of statements as long as a condition is true. Note: remember to increment i, or else the loop will continue forever. The while loop requires relevant variables to be ready, in this example we need to define an indexing variable, i, which we set to 1.

Dec 10, 2024 · 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.

In Python, we use a while loop to repeat a block of code until a certain condition is met. For example, print(number) number = number + 1. Output. 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 True. # body of while loop. Here,

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.

In Python programming, we use while loops to do a task a certain number of times repeatedly. The while loop checks a condition and executes the task as long as that condition is satisfied. The loop will stop its execution once the condition becomes not satisfied. The syntax of a while loop is as follows: while condition: statements

Feb 5, 2024 · In this article, we will examine 8 examples to help you obtain a comprehensive understanding of while loops in Python. Example 1: Basic Python While Loop. Let’s go over a simple Python while loop example to understand its structure and functionality: >>> i = 0 >>> while i . 5: >>> print(i) >>> i += 1 Result: 0 1 2 3 4

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. Python keyword while has a conditional expression followed by the : symbol to start a block with an increased indent.

Python While Loop is used to execute a set of statements repeatedly based on the output of a boolean expression. In this tutorial you will learn syntax and different usage examples for Python while loop.

The syntax of the while loop in Python is: while test_condition: statement(s) Here, the statements inside the while loop are executed for as long as test_condition is True .

Python supports having an else statement associated with a while loop. If the else statement is used with a while loop, the else statement is executed when the condition becomes false before the control shifts to the main line of execution. The following flow diagram shows how to use else statement with while loop −.
