![]() ![]() If the password is correct, the while loop will exit.While going through this loop, there are two possible outcomes: In this program, we’ll ask for the user to input a password. Let’s create a small program that executes a while loop. The something that is being done will continue to be executed until the condition that is being assessed is no longer true. In Python, while loops are constructed like so: while : If you don’t have a programming environment set up, you can refer to the installation and setup guides for a local programming environment or for a programming environment on your server appropriate for your operating system (Ubuntu, CentOS, Debian, etc.) While Loop You should have Python 3 installed and a programming environment set up on your computer or server. ![]() After an if statement, the program continues to execute code, but in a while loop, the program jumps back to the start of the while statement until the condition is False.Īs opposed to for loops that execute a certain number of times, while loops are conditionally based, so you don’t need to know how many times to repeat the code going in. You can think of the while loop as a repeating conditional statement. The code that is in a while block will execute as long as the while statement evaluates to True. We’ll be covering Python’s while loop in this tutorial.Ī while loop implements the repeated execution of code based on a given Boolean condition. One way to repeat similar tasks is through using loops. Computer programs are great to use for automating and repeating tasks so that we don’t have to.
