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 this example, the condition for while will be True as long as the counter variable (count) is less than 3.

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: statements.

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,

Feb 5, 2024 · These eight Python while loop examples will show you how it works and how to use it properly. In programming, looping refers to repeating the same operation or task multiple times. In Python, there are two different loop types, the while loop and the for loop.

Python lacks a built-in do-while loop, but you can emulate it using a while True loop with a break statement for conditional termination. With this knowledge, you’re prepared to write effective while loops in your Python programs, handling a wide range of iteration needs.

Jul 19, 2022 · To do something similar to this example, you would need to make use of Python's while loop. The general syntax for writing a while loop in Python looks like this: body of while loop containing code that does something. Let's break it down: …

Aug 18, 2023 · Infinite loops with counters and similar use cases can often be written more easily using these functions. A while loop in Python is written as follows: You can specify multiple conditions for the condition part with and or or. Use break to break a while loop.

In this tutorial, we learn how to write a while loop in Python program, and some of the scenarios where while loop is used, with the help of examples. The syntax of while loop statement is. statement(s) where. while is Python keyword, condition is a boolean expression, and statement (s) is a block of code.

Apr 23, 2025 · In Python programming, loops are essential control structures that allow you to execute a block of code repeatedly. The `while` loop is one of the fundamental loop types in Python. It provides a way to execute a set of statements as long as a certain condition remains true. Understanding how to use the `while` loop effectively is crucial for writing efficient and powerful Python programs.
