This shields you from the details of the Linux operating system. But finally we recommend " remote development" with an IDE that runs locally on your notebook/desktop. In this section we present current procedures for programming Python on the Raspberry Pi. Frustrations with the IDE and the lack of appropriate error messages may spoil your teaching efforts and break down interest and motivation for programming. Whatever you decide to use, do not underestimate the importance of a simple and stable development environment for beginners. We recommend P圜harm (by JetBrains) for the professional programmer and TigerJython (by Tobias Kohn) and Geany for occasional users, kids and students. There are several attempts to overcome this deficiency, but modern Python IDEs that are simple to use, but hides the ugly Python shell are still rare. In modern times where people are accustomed to sophisticated graphical user interfaces, this way of working is outdated. Then the Python interpreter is started that displays an old-style (black) terminal window and the script is loaded and executed using old-fashioned command lines. Because Python is an interpreted language, the development cycle is simple: Any text editor can be used to write the source program (often call a Python script). But the number and the quality of development environments for Python is still poor. Countless programs and library modules are available for all kind of activities using the GPIO interface. After writing text or introducing change to the file, the title bar will show Modified at the top right side.The main programming language for the Raspberry Pi is Python. Figure 9: Cut and Paste in Nanoįurthermore, a new and unnamed file will display new buffer on the title bar. Using these, you can already get the text in and out of Nano. This will bring out the usual copy-cut-paste options you see on standard word editors. In order to do that, you must press the Shift and Right Click button. Cutting and pasting using Nano shortcuts won’t let you get the text out of Nano to another software and vice versa. If you want to cut a selected text, simply type CTRL + K. So for example, if you need help, just type CTRL + G. The carets on the shortcuts stand for the CTRL button. You just type text directly and you always see the keyboard shortcuts under. You can just start nano by entering the nano command. Nano comes with Raspbian as a default editor so you don’t need to install it explicitly. It’s easy to use and offers a myriad of keyboard shortcuts, which are useful when writing in a computer’s CLI (Command Line Interface). GNU Nano is the native text editor of most Linux distros. Figure 6: Error HighlightingĪdditionally, you can click Check to search for errors on your code without running the program. Mu checks for errors and highlights them in red so you can detect coding mistakes without a problem. One useful feature of Mu is error highlighting. You will see the output on an integrated Python shell below the text editor. py on the file name as Mu already assumes the file type when you set the mode to Python 3. Let us now write the canonical Hello World program. For now, we are going to use it for Python programming. You can change them depending on what you intend to use Mu for. The current version of Mu offers 4 modes. One is by accessing Menu on the top left side of your desktop. There are two ways you can get Mu in your system. Installing Muīefore you install Mu in your Raspberry Pi, make sure your Raspbian OS is up to date by entering sudo apt-get update and sudo apt-get dis-upgrade in the terminal. It is known for being easy-to-use as its target users are beginner users. Mu is a text editor and IDE (Integrated Development Environment) specially made for Python programming. In this tutorial, we are only going to explore 1 of each kind: Mu for the desktop graphical editors and Nano for the command-line editors. Some of the command-line editors you can use on a Raspberry Pi are: They use keyboard shortcuts as an alternative to a point-and-click interface. Unlike desktop graphical editors, command-line editors can be used with only a keyboard. Some of the desktop graphical editors that you can use on a Raspberry Pi are::Ĭommand-line editors, on the other hand, can only be accessed using the Terminal. Moreover, to use a desktop graphical editor properly, you need to have a mouse and keyboard. You can access them through the Raspberry Pi Menu or the Terminal. Desktop graphical editors are text editors that have a GUI (Graphical User Interface).
