I still recommend IDLE (the Python IDE): not as editor (which is just so-so, and Linux has plenty of competent editors, imne preferred is SciTE), but as shell.Ĭompared to other languages, shell allows you to try language one line and one construct at a time, and see results immediatelly, instead of having to write small half-page programs just to try single feature, like you have to do in ie Java. pyc files, you can distribute them instead of sources - but source can be easily restored from them (sans comments of course) This code can be compiled further, but usualy is just executed by Python runtime.Ĭompiled code is in. Python is compiled into intermediate structure ("byte code") which is abstract machine like P-code or JVM. Python is not interpreted (in sense like you describe: "run line by line" - it was BASIC 25 years ago. Instead, you use another program (the "interpreter") that runs your program line by line. That means that the programs you write don't "run" directly. For example, you can usually run your program by pressing a button somewhere.įirst of all, Python is an interpreted language. But the advantage of an IDE is that you don't need to use the command line as much. IDE's are nice for some things, but all you really need in the end is a text editor. Eric is another one for Python, and I couldn't list all of the ones that support Python in addition to many others. IDLE is well known as a Python-only IDE, but there are plenty of alternatives. Don't use it lightly or with ignorance.Īn "IDE" is just a text editor with some other tools built in. Usually this is to perform various administrative tasks, like installing packages or changing system files. Do not run gedit with sudo, or anything else, unless you know why. "sudo" is used to run programs as the administrator, and you should be careful when using it. Look for the checkbox for "executable" and see that it's checked. To mark a program as something that can be run, use this command: Then the file named myscript.py will be run.Īlternatively, if you mark your script as executable, you can just run it like this: The interpreter for Python is named "python". Edit: wow, three people beat me.įirst of all, Python is an interpreted language. Scientists need more interactivity when analysis their data: this is why ipython was created.Oh dear, another beginner. For all these reasons, the default python command-line interpreter is only used for very small tasks like testing a command or two. Some important functionalities are missing: some are cosmetic (like colors), some are very useful (like automatic code completion with or the possibility to paste several lines of code at once). The default command-line interpreter comes with some functionality (for example, if you use the up and down arrows you can navigate in your previous commands) but this functionality is very sparse. This functionality is called REPL, and it's a feature, of modern interpreted languages. On line 3 we used the print() function to display the output of our computations, but as it turns out it is not necessary: the command line shell will print the output anyway. We defined variables, and did some arithmetics with them. This should look quite familiar to you, whatever language you learned before.
