Before you can start programming in Python 3, you need to install it. If you’re running Linux at home, you may already have Python 3, too. Most popular GNU/Linux distributions come with Python 2 in the default installation; a small but growing number of distributions also include Python 3. Mac OS X includes a command- line version of Python 2, but as of this writing it does not include Python 3. Microsoft Windows does not come with any version of Python. But don’t despair! You can point- and- click your way through installing Python, regardless of what operating system you have. Once you’re at a command line prompt, just type python. ENTER, and see what happens.

Installing WindowBuilder Pro. All downloads are provided under the terms and conditions of the Eclipse Foundation Software User Agreement unless otherwise specified. The Perl for MS Windows, free of charge! Perl is a programming language suitable for writing simple scripts as well as complex applications - see https://www.perl.org. On my home Linux system, Python 3. Python interactive shell. Of course, there are lots of different versions of Windows — XP, Vista, Windows 7 — but Python runs on all of them. The more important distinction is 3. If you have no idea what architecture you’re running, it’s probably 3. Your choices will look something like this. I don’t want to include direct download links here, because minor updates of Python happen all the time and I don’t want to be responsible for you missing important updates.
You should always install the most recent version of Python 3. Windows will pop up a security alert, since you’re about to be running executable code. The official Python installer is digitally signed by the Python Software Foundation, the non- profit corporation that oversees Python development. Don’t accept imitations! The default choice is “install for all users,” which is the best choice unless you have a good reason to choose otherwise. But then, why are you installing Python without permission from your company’s Windows administrator? ![]() ![]() Don’t get me in trouble here!). Click the Next button to accept your choice of installation type. The default for all versions of Python 3. C: \Python. 31\, which should work well for most users unless you have a specific reason to change it. If you maintain a separate drive letter for installing applications, you can browse to it using the embedded controls, or simply type the pathname in the box below. You are not limited to installing Python on the C: drive; you can install it on any drive, in any folder. ![]() ![]() Like many installers, you have the option not to install every single component of Python 3. If disk space is especially tight, you can exclude certain components. Recommended but not required. I strongly recommend keeping this option. Recommended if you are on dialup or have limited Internet access. Required if you want to learn about migrating existing Python 2 code to Python 3. If you have no existing Python 2 code, you can skip this option. We will not use it in this book, nor have I ever used it in the course of programming in Python. Completely optional. The installer will list your drive letters, compute how much space is available on each drive, and calculate how much would be left after installation. Within that, there is a program called IDLE. Select this item to run the interactive Python Shell. Older Macs used Power. PC chips. You don’t need to understand the difference, because there’s just one Mac Python installer for all Macs. It will be called something like Python 3. Mac Installer Disk Image, although the version number may vary. Be sure to download version 3. It will be named something like python- 3. The disk image contains a number of text files (Build. License. txt, Read. Me. txt), and the actual installer package, Python. If you are still running Mac OS X 1. Apple no longer provides security updates for your operating system, and your computer is probably at risk if you ever go online. Also, you can’t run Python 3. Python is open source, and its license is approved by the Open Source Initiative. Python has had a number of owners and sponsors throughout its history, each of which has left its mark on the software license. But the end result is this: Python is open source, and you may use it on any platform, for any purpose, without fee or obligation of reciprocity. Since Python is open source, you are really “agreeing” that the license is granting you additional rights, rather than taking them away. You must install Python on your boot drive, but due to limitations of the installer, it does not enforce this. In truth, I have never had the need to change the install location. If you want to do this, click the Customize button; otherwise click the Install button. This is the guts of Python, and is both selected and disabled because it must be installed. I strongly recommend keeping this option selected. I strongly recommend keeping this option, too. Recommended if you are on dialup or have limited Internet access. You probably don’t need to change this. This would be very bad, since most of those scripts are written for Python 2, and they would fail to run properly under Python 3.). Click the Install button to continue. There is no way to install Mac Python without administrator privileges. The most important piece is IDLE, the graphical Python Shell. Examples throughout this book will assume that you can find your way into the Python Shell. The exact details vary by distribution. In Ubuntu Linux, the easiest way to install Python 3 is through the Add/Remove application in your Applications menu. Some are already installed; most are not. Because the repository contains over 1. The default filter is “Canonical- maintained applications,” which is a small subset of the total number of applications that are officially supported by Canonical, the company that creates and maintains Ubuntu Linux. You’re going to check two packages. ![]() Installation¶ Spyder is quite easy to install on Windows, Linux and MacOS X. Just the read the following instructions with care. How to install JDK on Windows? Environment Used. Java SE 6 Update 29; Windows (XP/Vista/7) OS; Downloading Java Development Kit (JDK). The easiest way for drivers to do their daily log on a laptop computer. Eclipse and Dieselboss bring you the Drivers Logbook software program. ![]() The first is Python (v. This contains the Python interpreter itself. This is a graphical Python Shell that you will use throughout this book. From here, you can double- click IDLE to launch the Python Shell, or click the Close button to exit the package manager. Examples throughout this book will assume that you can find your way into the Python Shell. In particular, it is available in virtually every Linux, BSD, and Solaris- based distribution. For example, Red. Hat Linux uses the yum package manager. Free. BSD has its ports and packages collection, SUSE has zypper, and Solaris has pkgadd. A quick web search for Python 3 + your operating system should tell you whether a Python 3 package is available, and if so, how to install it. The graphical Python Shell (named IDLE) also contains a decent text editor that supports Python syntax coloring and integrates with the Python Shell. If you don’t already have a favorite text editor, you should give IDLE a try. The Python Shell itself is an amazing interactive playground. Throughout this book, you’ll see examples like this. The three angle brackets, > > > , denote the Python Shell prompt. Don’t type that part. That’s just to let you know that this example is meant to be followed in the Python Shell. You can type any valid Python expression or command in the Python Shell. Don’t be shy; it won’t bite! The worst that will happen is you’ll get an error message. Commands get executed immediately (once you press ENTER); expressions get evaluated immediately, and the Python Shell prints out the result. As it happens, 1 + 1 is a valid Python expression. The result, of course, is 2. But there’s lots more you can do in the Python shell. If you ever get stuck — you can’t remember a command, or you can’t remember the proper arguments to pass a certain function — you can get interactive help in the Python Shell. Just type help and press ENTER. You can get help about a single object, which just prints out the documentation and returns you to the Python Shell prompt. You can also enter help mode, where instead of evaluating Python expressions, you just type keywords or command names and it will print out whatever it knows about that command. This reminds you that you’re in the interactive help mode. Now you can enter any keyword, command, module name, function name — pretty much anything Python understands — and read documentation on it. While it’s useful to get started with learning the language itself, many developers prefer other text editors or Integrated Development Environments (IDEs). I won’t cover them here, but the Python community maintains a list of Python- aware editors that covers a wide range of supported platforms and software licenses. One that does is Py. Dev, a plugin for Eclipse that turns Eclipse into a full- fledged Python IDE. Both Eclipse and Py. Dev are cross- platform and open source. It has per- user licensing, but students can get a discount, and a free time- limited trial version is available. There’s no right or wrong way to develop in Python. Find a way that works for you!
