Join Joe Marini for an in-depth discussion in this video Loops, part of Up and Running with Python.
Repeating code over and over again via a construct known as a loop is also a fairly…common scenario in programming. And Python provides a couple of ways of…doing that, which we're going to take a look at now.…So let's open up loops_start.py. And you can see I've got a stub doubt…function here called main. And a variable named x which I'm…initializing to zero. Over here in example snippets.…We're going to come down to the loop section.…And let's start by copying lines 105 through 108.…
Okay, so we'll copy those and we'll paste them in here below the x definition.…Okay. So this is a while loop.…And the contents of the while loop, and again you can see that it's indented.…So that indicates that these lines of code belong to the while loop and not up here…in the main part of the function. So a while loop executes while the…condition contained inside these parenthesis is true.…
So while x is less than 5, we're going to print the value of X, and then we're going…to increment X by 1. Now some languages like C, provide a whole…
