In this lesson, we are going to set up Python and the idle development environment. To do that, we need to go to www.python.org. Once we're here, we want to go to downloads, then we want to go to Windows, and what we're going to look for is the latest stable release. Now, the thing about open source software is that they're always experimenting on it. So there's always releases and these are more for the very serious operating system type programmers who live to find bugs and fix them and that sort of thing. We are more geared towards the development side, so we want a stable release so that we are able to make stable program, reduce our mistakes, and leave as little to chance as we can. So our stable release is going to be Python 3.9.0, and this was released on October 5th. So that was merely a couple days ago, but that means it's been through all the testing, and this is what we want. So we're going to click that file and we're going to kind of, we don't really need to read these white papers on what's going on. What we want to do is we want to actually download the environment. So the one we want to get is we want to get the Windows x86 executable installer. So we'll click that, and we're going to go ahead and save this file to our desktop, and it really won't take that long to download as the file is only 25 megabytes. So now we can x out of here, and here is our installer. Double click the installer. Now we might see a couple of little things that are different. I have Python already installed, but this is a newer version. It might overlook or tell me I have one on my machine already, but we'll cross that road when we come to it. So we want to install the launcher for all users, and make sure we add Python 3.9 to the path. So now we want to install now, and this includes the idle development environment. As this is installing, I would like to point out that a few of you may be thinking, why are we installing a 32-bit piece of software on a 64-bit machine? The reason for that is we want the latest and most stable install of Python. So if it's 32-bit, we're going to take it. The difference between the 32-bit and the 64-bit is that it may run just a little bit slower, but for the programs we're going to be writing in this initial course, 32-bit will be just fine for us. And then we can hit close, and now we have it installed. So let's just take a look and see what it looks like. If you get down into your search bar in Windows, type in idle, ideally. This is what you should see. In our next lesson, we are going to talk about setting up a new file and input and output. See you then.

Course Description

Python programming is an object oriented, interpreted scripting language that works well for handling complex data relationships, automation, AI, and more. This introductory Python course shows how to set up Python and a programming interface called IDLE. You’ll learn how to set up the environment, accept input, and display output. You’ll also learn about variables in Python and variable names, types, and the assignment operator. Finally, you’llsee how to combine variables with strings in Python.

What You'll Learn

Set up Python and the IDLE programming interface, including configuring the development environment
Accept input and display output in Python
Define what a variable is and create valid variable names
Work with variable types and use the assignment operator
Combine variables with strings and combine output in Python
Understand what Python is and what it is used for
