No more excuses, because Python is the perfect way to get started! rg o s. e n zi a Python is a great programming language for both beginners and experts. It is designed with code readability g in mind, making it an excellent choice for beginners who are still getting used to various programming concepts. The language is popular and a has plenty of libraries available, allowing programmers to get a lot done with relatively little code. You can make all kinds of applications in Python: you could use the Pygame framework to write 2D games, you could use the GTK libraries to create a windowed or you could try something llmsimpleapplication, a little more ambitious like an app such as creating one using Python’s Bluetooth and Input libraries to capture the input from a USB keyboard and relay the input events to an Android phone. .a For this tutorial we’re going to be using Python 2.x since that is the version that is most likely to be installed on your Linux distribution. tutorials, you’ll learn how to create popular games using In the following w Python programming. We’ll also show you how to add sound and AI to these games. w w 8 Get started with Python g a llm .a w w rg o s. e n zi a w 9 Getting started Hello World rg o s. e n zi a Let’s get stuck in, and what better way than with the programmer’s best friend, the ‘Hello World’ application! Start by opening a terminal. Its current working directory will be your home directory. It’s probably a good idea to make a directory for the iles that we’ll be creating in this tutorial, rather than having them loose in your home directory. You can create a directory called Python using the command mkdir Python. You’ll then want to change into that directory using the command cd Python. The next step is to create an empty ile using the command ‘touch’ followed by the ilename. Our expert used the command touch hello_world.py. The inal and most important part of setting up the ile is making it executable. This allows us to run code inside the hello_ world.py ile. We do this with the command chmod +x hello_world. py. Now that we have our ile set up, we can go ahead and open it up in nano, or alternatively any text editor of your choice. Gedit is a great editor with syntax highlighting support that should be available on any distribution. You’ll be able to install it using your package manager if you don’t have it already. g a llm .a w w [
