Welcome to a tutorial explaining functions. This article will help clarify some things we have already been exposed to such as function prototypes, function calls, return values, etc.
Welcome back! In the last iteration of how to train your python, we covered error detection and handling. Today we'll be diverging from this and discussing functions.

Welcome back to another tutorial on functions. Last time, we looked inside memory to see what functions looked like in the flesh and all that Assembly was pretty nasty. At least you have some exposure to it. This time, we will be examining how functions work with the stack.
Hello there! This will probably be the final tutorial on functions where we will be looking over a method called pass by reference. This technique allows us to modify large amounts of data without the overhead and return multiple values. Let's go!
In the last tutorial, we learned how to make functions and how they work on the high level. This time, we will take a peek under the hood again, stare deep into its soul and see its ugliness face to face to see how it works in the lower level.
Mac keyboards are great when listening to music or watching a movie, since you can control what's playing without going back into iTunes or QuickTime Player. However, when you're using an app like Photoshop that uses the F7, F8, and F9 as shortcuts, it gets pretty annoying to have to hold down the Fn key. Why can't you just hit the back, play/pause, and skip buttons alone?
Hello again, and welcome back to another tutorial on functions, this time, covering recursion. What Is Recursion?

Blue light (like that from our smartphone) tricks the human brain into thinking it's still daytime, even if it's coming from something as small as a screen. So while you're playing around with your new Pixel or Pixel XL after dark, subconscious signals to be awake are preventing you from getting to sleep as early as you should.
For the most part, when you're copying text on your Android device, it's because you intend on pasting it into a different app than the one you're currently using. For instance, you might be looking at a posting on Craigslist. So you copy the seller's phone number, then head to your home screen, switch over to your phone app, paste it into your dialer, and finally make the call.
There are over 1.6 million apps on the Google Play Store, which makes it the largest collection of mobile apps on the planet.

Gatorade: its popular red flavor can stain the whitest fabric, and its sweet taste is oddly refreshing after breaking a sweat. If you've ever participated in a sport, you probably spent halftime at games and practice breaks chugging the stuff. Though it made its name as a sports drink, Gatorade is also a well-known hangover helper—but its beneficial and interesting uses don't end there. The brightly colored drink can do so much more than just hydrate you.
If you use Goals in Google Calendar, you've probably already received the notification that Google, in typical executioner fashion, has marked the feature for death. As of November 2022, you can't create new goals, and your current goals won't repeat anymore. Google suggests switching to repeating events or tasks, but there's a better option to use on your Android and iOS device.
