English In this video we're going to go ahead and download and install Python or rather get Python 3 working on this computer. Now we don't actually have to download and install anything on most Linux distros and that's because it normally comes pre-installed with both Python 2 which we won't be using in this course and the newer Python 3, so to confirm that till you've got python on your Linux distribution and I'm running a bunty Linux 16.04 in this example, just open a terminal or command window I'm going to click on terminal and so you can then type Python to see whether something comes up and you can see in my case I haven't actually installed anything but Python 2 was installed as a default program with this version of Ubuntu Linux. So version 2 as I mentioned isn't what we're going to be using in this course, so I'm going to do a ctrl D to exit out of that. The other thing we can check it is we can type Python and then the number 3 on the end without any spaces press enter and that also shows that we've got Python 3 installed as well. So you can see there's two separate versions that are already installed meaning that unlike the Windows and Mac versions, we don't need to do any installation, we can use the version of Python that is already installed. Now Python does get updated and in fact if you went to the website right now for python.org, you'd see that the latest version is python 3 point six point two, so we've got a slightly older version but look it'll work just fine in this course and there's no sort of reason not to rush an upgrade and just a warning actually if you are thinking about doing that, be careful because python is heavily used within the GUI of many Linux distributions. So if you accidentally uninstalled Python or start you know installing different versions and so on and so forth you can get yourself into a situation where Linux won't boot or at least I won't have a GUI interface and that can be really difficult to recover from. So for that reason our recommendation is just to stick with the version of Python that is already in your Linux distribution, so long as it's three points something in my case you can see I've got three point five point two, we're actually good to go. Alright so I'm going to do a control d to get out of that, the other thing we need is something called idle which is an editor that we're going to be using at least early in the course to test some Python code out. So we can type in idle, idle and that doesn't work because it hasn't been installed and that would have been the older version that suits Python 2 and Python 3 would use something called idle 3 but you can see that's also not installed, so we need to go through the process of installing that for a Ubuntu Linux, so to do that I'm going to type in sudo apt - get a space between those two words space install space idle3 or idle3 press enter, I'm going to type my password, I can top it. Okay, so now go through and it's actually asked if I want to install it so I'm going to push yes or top y and press enter it's going to go ahead and install idle3 for us and you'll be seeing how to use that program in the next video. Now it's complete as you can see there, so I can then just go ahead and type idle 3 and you can see that's now popped up a Python shell and within that window now we can start typing some Python commands but I'm going to finish the video here now. In the next video we'll go ahead and start using this Python shell to type in a few commands so see you in the next video.
