While Loops in Python A while statement in python sets aside a block of code that is to be executed repeatedly until a condition is falsified. The structure of a while loop allows the total number of iterations, or repetitions, to be unknown from the start. Examples of use cases might be...
A while can also be used along with an else statement. In this as soon as the loops or the iterations get over, the python code will execute the else statement i.e. the code under it. It is important to know that, if there is any error or break inside the else statement then the...
This article covers the construction and usage of While loops in Python. While Loop In Python A while statement iterates a block of code till the controlling expression evaluates to True. While loop favors indefinite iteration, which means we don't specify how many times the loop will run in...
Sometimes we want a part of the code to keep running, again and again, until we are ready for it to stop. Let’s see how while loops can help us do this! Python While 1 Run the example: In this code, we import time so we can use a “wait” function called sleep() . Then, ...
Python 2.5 While Loops while Loops#while循环 An if statement is run once if its condition evaluates to True, and never if it evaluates to False. A while statement is similar, except that it can be run more than once. The statements inside it are repeatedly executed, as long as the ...

Of course, if you know any other programming languages, it will be very easy to understand the concept of loops inPython. In this article, I shall highlight a few important examples to help you know what a while loop is and how it works. ...
Another common and extended use case of while loops in Python is to create event loops, which are infinite loops that wait for certain actions known as events. Once an event happens, the loop dispatches it to the appropriate event handler. Some classic examples of fields where you’ll find ...
