Lesson Details:

I: Introduction

A: Learning the basics of programming languages is one of the most useful skills that you can learn in today’s digital age. As more and more processes are automated, it is important to understand what is happening behind the scenes.

A: Programmers are the people who write computer programs. It is an extremely complex skill, one that most people will never master. But this does not mean that you cannot learn the basics. Here, you will learn how to program in python. You will then go on to create a simple program that can solve simple mathematical problems for you.

1. Learn basic python programming for beginners

A: One of the very first things that you need to know about computer programming is that it is not easy. It takes a lot of practice to get good at it, but luckily there are plenty of resources available online to help you. Here, we will look at some basic python programming syntax so you can start writing your own simple programs.

A: Python was developed by Guido Van Rossum back in 1991. It was created with the intention of being easy to learn, read and use. It was designed with simplicity in mind, making it extremely accessible for beginners. There are many different versions of the language, but the most common are version 3 and version 2.7. The official website for python can be found at python.org. Here, you will find all sorts of useful information including documentation, tutorials and more.

A: To begin with, open up your web browser and visit the python.org website. Scroll down the page until you reach the Downloads section. This is where you will find direct links to download the various versions of python that are available. These include versions 2.7 and 3.4+. You can choose either of these versions, or both if you want to experiment with different versions of the language. Downloading python is easy; just click on the link associated with your operating system (for example Windows) and select Save File. Once it is done downloading, double click on the installer and follow the instructions onscreen to install it onto your computer.

A: Next, you need to be able to see what you are typing in order to know if it is correct or not. If you are using Windows, open up your Control Panel and select “Programs” followed by “Accessories” followed by “Text Editor”. This opens up Notepad which you can use to write your python programs. If you are using Mac OS X, open up TextEdit which also has basic text editing functionality. If you are using Linux, you should already have something installed on your computer for this purpose which you can use instead.

A: Let’s start off with a simple program to get you started with python programming syntax. Open up notepad or your text editor of choice and type in the following code:

print("Hello World!")

Save the file as “sampleprogram” and ensure that it is saved with a .py extension. This tells the computer that this file contains python code, rather than something else like a document or an image file. Now that you have written your first python program, run it by pressing Ctrl + O on Windows or Command + O on Mac OS X while the program is highlighted in Windows Explorer or Finder on Mac OS X. You should see Hello World! printed on screen in response to this command. Congratulations! You have just written your first python program!
