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.
5 lut 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.

Basic Structure Of Loops. Whether or not a part of a program repeats is determined by a loop control (typically the control is just a variable). Initialize the control to the starting value. Testing the control against a stopping condition (Boolean expression) Executing the body of the loop (the part to be repeated) Update the value of the control.
Loops in Python V22.0002-001 Summary • Loops provide a way to repeat blocks of instructions • While loops are the most general –They require a condition for exiting the loop •If the condition is never true, the loop is endless • For loops provide a simple way of repeating a block –once for each element in a sequence
