I was wondering what is best from these two enablers of interactive python or iPython. Either using emacs-ipython-notebook or SCIMAX. I understand that both accomplish quite the same thing, but can't decide which one to use and have no time to start checking. So if someone has checked already, much appreciated. Thanks.
Scimax is a complete emacs distro. Meaning a complete Emacs environment, a complete setup. If that is what you are after, it is well maintained by jkitchin in: https://github.com/jkitchin/scimax
EIN (Emacs ipython Notebook) maintained here, Is a notebook solution. little configuration is required. It is a package like any Emacs package.
org-babel Worth mentioning too, look for ob-python or ob-ipython, if you are using org it is a natural way to include code the literate way. It is what I ended up using . Have a look at:
https://github.com/gregsexton/ob-ipython
And also at:

I recently installed IPython after hearing about it on this forum. I am looking for an environment that is similar to what might come with MATLAB or RStudio for R.
I was under the impression that IPython would give me that but the version I downloaded for Windows looks very bare. In fact I do not really see a difference between IDLE and IPython except tab completion and history (which I have been wanting) but this is about as much as the interpreter that comes with R which I used to think was hard to work with.
Have I misunderstood the point of IPython? Or is it possible that I have not installed correctly?
I have also downloaded the 'Console' and while I am not convinced that it is working properly, it looks very bare as well.
Komodo looks good but is somewhat costly. Netbeans and Eclipse also look good, but do not seem to be straightforward to install, at least for somebody with my level of knowledge, so it would be good if somebody could verify their compatibility with Python, features, and ease of use for a non-expert user.
I suggest you try Spyder
You can find it here : https://www.spyder-ide.org/
It is perfect for you : it is a lightweight Scientific IDE with the explicit purpose of being similar in feel to matlab.
It has an editor, a console and lots of neat features and plug-ins.
It can use IPython as its console.
IPython is "just" an enhanced python console with pure awesomeness built-in. (actually it's much more : it's a client-server architecture with multiple interfaces to pure magic, in console mode, Qt, and even inside a browser with the Notebook)
Definitely check it out later on when you've used the basic console for a while.
For the context, i've been using Eclipse, pycharm, got tired of those, and i started to ask around what people use, and the one i've heard the most about is sublime text.
You should take a look, maybe it's what you are looking for!
I just saw it's not open source though!
What i'm using now is Ninja-IDE, which is written in python and is open source and seems pretty good! It has plenty of plugins, which includes an IPython plugin
Have you tried the qtconsole backend? It was released after you asked your question.
This is a very lightweight widget that largely feels like a terminal,
but provides a number of enhancements only possible in a GUI, such as
inline figures, proper multiline editing with syntax highlighting,
graphical calltips, and much more.
From the Windows command prompt, enter:
ipython qtconsole
I am trying to incorporate an autocomplete feature in Vim. I have used the omnicompletion of Vim as well as Pydiction. But in both the cases this message pops up:
Omni completion (^O^N^P) Pattern not found
I have tried Vim's Omnicompletion with Python just doesn't work. But this is not helping. Is there a workaround?
Try Jedi! There's a Vim plugin at https://github.com/davidhalter/jedi-vim.
It works just much better than anything else for Python in Vim. It even has support for renaming, goto, etc. The best part is probably that it really tries to understand your code (decorators, generators, etc. Just look at the feature list).
As pointed out by in the comments, this answers is outdated. youcompleteme now supports python3 and jedi-vim no longer breaks the undo history.
Original answer below.
AFAIK there are three options, each with its disadvantages:
youcompleteme: unfriendly to install, but works nice if you manage to get it working. However python3 is not supported.
jedi-vim: coolest name, but breaks your undo history.
python-mode does a lot more the autocomplete: folding, syntax checking, highlighting. Personally I prefer scripts that do 1 thing well, as they are easier to manage (and replace). Differently from the two other options, it uses rope instead of jedi for autocompletion.
Python 3 and undo history (gundo!) are a must for me, so options 1 and 2 are out.
This can be a good option if you want python completion as well as other languages. https://github.com/Valloric/YouCompleteMe
The python completion is jedi based same as jedi-vim.
I tried pydiction (didn't work for me) and the normal omnicompletion (too limited). I looked into Jedi as suggested but found it too complex to set up. I found python-mode, which in the end satisfied my needs. Thanks #klen.
I found a good choice to be coc.nvim with the python language server.
It takes a bit of effort to set up. I got frustrated with jedi-vim, because it would always freeze vim for a bit when completing. coc.nvim doesn't do it because it's asyncronous, meaning that . It also gives you linting for your code. It supports many other languages and is highly configurable.
The python language server uses jedi so you get the same completion as you would get from jedi.
Use install coc.nvim package and CocInstall coc-pyright
if you are using vim-plug:
Plug 'neoclide/coc.nvim'
:PlugInstall
CocInstall coc-pyright
I ran into this on my Mac using the MacPorts vim with +python. Problem was that the MacPorts vim will only bind to python 2.5 with +python, while my extensions were installed under python 2.7. Installing the extensions using pip-2.5 solved it.
Could anyone tell me how to use pure Python without Cocoa support in Xcode? I can only find the Cocoa-Python template on the Internet.
Thanks in advance.
If you are just trying to write pure Python command line tools, using Xcode is like using a big sledge hammer to hit a tiny nail, in other words, probably not the best tool for the job. There are some old posts out there about how to set up a pure Python Xcode project, like this one, but, in the end, you might be better off using an editor you're already familiar with, like emacs, or, if you don't mind spending a little bit of money, TextMate, all along with a free vcs like mercurial or git. Or take a look in MacPorts for those and other options.
Just about the best IDE for editing and running Python code is actually still emacs. The python-mode for emacs does a wonderful job of maintaining whitespace and, with a bit of configuration, emacs is truly a powerful editor.
Pretty radically different than your typical GUI editor, certainly, and some find it quite distasteful. I've personally used emacs, mostly, for editing Python since 1992 or so.
Google will reveal all, including a native version of Emacs for Mac OS X.
A lot of people like eclipse with PyDev for python, although I don't know how wel it works on OS X with apple's mishandling of java.
Even though I am using BBEdit, I found Wingware Python editor did a good job in exploiting the introspected data of Python modules. Purely designed for Python. Give it a try.
http://www.wingide.com/
I'm a complete newbie to Python. I've worked on PHP/JavaScript earlier but starting today I'm moving onto Python. I have no idea about the environment needed for it. I could use some suggestions on it for me to get started.
Under Unix, Emacs is a good choice, to which I always come back, because it is convenient to have a single editor for everything, and because it's open source.
What is best for you depends on your past experience with IDEs. I'd say: stick with what you've been using, or take this opportunity to try an even better IDE.
Note: Python comes with Idle, which is a very simple (if limited) IDE.
Be sure to check out IPython. It's an enhanced interactive python shell with a bunch of useful features such as Tab-Completion using introspection (eg, type "my_object." to see a list of its attributes and methods), logging your interactive session to an executable python-file, defining macros, etc. The documentation page has a link to the tutorial as well as screencasts showing it in action.
On my mac/Linux machines, python came pre-installed. On windows I use both jython under the eclipse IDE and ActivePython with their IDE/eclipse. With eclipse you'll want PyDev.
It all depends on what you are looking for and what you are already using.
For instance, if you are using a more 'simple' editor at the moment: as long as it's got Python syntax you've got the basics.
If you are used to e.g. Eclipse you can just continue to use that, combined with Pydev. Besides syntax highlighting you'll also get more fancy features to help you debug and refactor your code.
Personally I use Emacs with python-mode (and a few other modes to interface with Subversion and Git). In the past I used Vim which also worked quite well.
My advice would be to start out with your current environment as long as it has some rudimentary support for Python. Once you are familiar with the language, start exploring what your environment is missing and either add it or if you cannot, switch to an enviroment which does support the feature.
I use gvim with some plugin in order to have better support for python.
If you like IDE, look at wing IDE wich is the best I have tested so far. Especially the debuger included is really helpful.
The Python Beginner's Guide and the official Python Tutorial both seem like good places to start.
Geany is a good option for a Linux setup, it's intellisense isn't that great but syntax highlighting is good and it can compile your code directly from inside the editor, plus it handles other languages such as C/C++, PHP, Java etc... Eric is another popular choice as it's a full IDE and I know some people use Eclipse.
On windows I use Notepad++, but it's mostly because I like text editors instead of fully blown IDE's.
Reference wise Daniel's choices are very good places to start, also check out Green Tea Press who do free computer books, there are two Python choices on there but the "Python for Software Design" book hasn't yet been published properly although you can download the manuscript. The "How to Think Like a Computer Scientist" book is a good one and not as scary as it sounds.
IDLE is nice to try out things. Other tools that people like are Eclipse with the Pydev plugin which seems to work ok, although it has crashed a few times (Eclipse, that is) and NetBeans (which I haven't tried) but some people seem to like.
I can only help you if you're running a Mac. Download Xcode. I believe that Python 2.3 comes bundled with these development tools. Luckily enough, this is all you really need to get started, unless you want a newer version of Python.
All you need to do is open up Terminal and type python. You're done!
I'm looking for a suite of plugins that can help me finally switch over to vim full-time.
Right now I'm using Komodo with some good success, but their vim bindings have enough little errors that I'm tired of it.
What I do love in Komodo, though, is the code completion. So, here's what I'm looking for (ordered by importance).
Code completion, meaning: the ability to code complete modules/functions/etc. in any module that's on the pythonpath, not just system modules. Bonus points for showing docstrings when completing.
Jump-to a class definition. I'm guessing CTAGS will do this, so how do you all manage automatically updating your tags files?
Project type management for managing buffers: ideally the ability to grep for a filename in a directory structure to open it. Bonus for showing an index of class definitions while a buffer is open.
Bzr integration. Not super important, since most of it I can just drop to the shell to do.
Here you can find some info about this.
It covers code completion, having a list of classes and functions in open files. I haven't got around to do a full configuration for vim, since I don't use Python primarily, but I have the same interests in transforming vim in a better Python IDE.
Edit: The original site is down, so found it saved on the web archive.
And I write another plugin: https://github.com/klen/python-mode
Old (now its more powerful) screencast here: https://www.youtube.com/watch?v=67OZNp9Z0CQ
Old question, but I typed all this up for a misread question...
General plugin recommendations: LookupFile and a plugin for your source control system (I like Git and Git-Vim).
Python plugin recommendations: If you're using Linux, I'd recommend ipython and ipy.py (a better interactive interpreter). Improved syntax highlighting, snippets, pydoc, and for refactoring support bicyclerepairman. I got started with this post.
You may want to try looking through someone's vimfiles. Mine are on github.
For refactoring: ropevim
Here is some info on Bazaar integration if you're interested:
https://launchpad.net/bzr-vim-commands
I use pydoc.vim (I actually wrote it) a lot, try it and tell me what you think. Another one that I think is quite useful is the updated syntax file with all it's extensions that you can enable, which you can find here.
I use Pydiction (http://www.vim.org/scripts/script.php?script_id=850) it's a plugin for vim that lets you Tab-complete python modules/methods/attributes/keywords, including 3rd party stuff like Pygame, wxPython, Twisted, and literally everything. It works more accurately than other things i've tried and it doesn't even require that python support be compiled into your Vim.
Code completion: PySmell looks promising. It's work-in-progress, but alredy useful.
I personally thinkJedi Vim is the best, but it is incompatible with python-mode.
