Installing Python plugin with WebStorm

Is there a way to install the Python plugin on WebStorm?
Some StackOverflow posts say to go to project settings (or project structure), then go to "modules", but I think that is just for IntelliJ and not specifically WebStorm, as I can't seem to find it.
I also downloaded https://plugins.jetbrains.com/plugin/631-python, but when I try to "Install plugin from disk" on the .zip file, it says
plugin python is not compatible with this installation.

That is not possible: this plugin is not compatible with WebStorm (as WebStorm does not have other plugins/functionality that is needed for Python plugin).
List of supported IDEs is clearly written at the top of that page:
If you need full Python support, have a look at PyCharm -- JetBrains IDE for Python: https://www.jetbrains.com/pycharm/
If you just want some syntax coloring for Python code: have a look at this answer: https://stackoverflow.com/a/25545919/783119
Also: https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000634624-Python-support-for-webstorm

I found a way to run a python script in webstorm. I needed it to run the backend part of the project. I add node configuration to run configuration and edit interpreter to python path
This is the node configuration:

How can I add a Python version to the Python Launcher?

On Windows, how can I add a Python version to the Python Launcher? I have python 3.7 installed alongside 2.7. I've made sure that the PATH variable and the registry keys are correct. One thing I will say is that I can't see any other Python environment variables on my machine (such as PYTHONPATH), or either of the py.ini files descibed here.
If possible, I would like the solution to also work with python distribition, such as Anaconda.
This is the same question as py launcher does not find my Python 2.7, but none of the answers worked for me, so I trust I am allowed to ask again.

How should I set the default Python version in Windows

I solved the problem by going to Control Panel -> Uninstall A Program, right clicking on "Python 2.7.15", clicking "change", and pressing "repair". No clue why I didn't try that first.

Using Python OpenMDAO in an IDE (PyScripter)

I'm trying to use the OpenMDAO package in the PyScripter IDE, running Python2.7 on Windows 8. But trying to import openmdao I'm returned with the error "No module named openmdao". The OpenMDAO installation instructions say to (i) run the go-openmdao.py script, and (ii) enter Scripts\activate.bat. How do I do (ii) in PyScripter, or any IDE for that matter?
Thank you,
Alex

I've been able to use OpenMDAO in an IDE (Spyder) by changing the path to the Python executable in the Spyer preferences from the default system binary to the one inside of the virtualenv directory. If you can do this, the IDE will be operating within the virtualenv, and OpenMDAO should become importable. This should also work for any other python virtualenv that you would like to use within an IDE.

I have used it with PyCharm. It works very well. You can import the virtual environment created by openMDAO in the preferencies/project/interpreter/add local.
PyCharm community version is free and has a nice debugging support, so I can recommend it for beginners in python.
I never heard about PyScripter, but if there is a place where you can change the default python executable to the one in openmdao/Script, that might work.

Python Code Completion

After using C# for long time I finally decided to switch to Python.
The question I am facing for the moment has to do about auto-complete.
I guess I am spoiled by C# and especially from resharper and I was expecting something similar to exist for Python.
My editor of choice is emacs and after doing some research I found autocomplete.pl, yasnippet and rope although it is not clear to me if and how they can be installed in a cygwin based system which is what I use since all the related documentation appears to be linux specific...
The version of emacs I currently use is 23.2.1 which bundles the python mode that although useful is far behind from whatever research has to offer.
My question to python users has to do about how common is autocomplete vs manual typing (using M-/ where possible) ?
I am thinking about just memorizing python build-in functions like len, append, extend etc. and revert close to a pre-autocomplete editing mode. How different such an approach is from what other pythonistas are doing?

I found this post
My Emacs Python environment
to be the most useful and comprehensive list of instructions and references on how to setup a decent Python development environment in Emacs regardless of OS platform. It is still a bit of work to setup but at least it covers the popular packages and components generally recommended for Python in Emacs that provide auto-completion functionality.
I loosely used this post as a guide to do the setup on my Windows machine with Emacs 23.2.1 and Python 2.6.5. Although, I also have Cygwin installed in some cases instead of running the *nix shell commands mentioned in the post, I just download the packages via a web browser, unzip them with 7zip, and copy them to my Emacs' plugin directory.
Also, to install Pymacs, Rope, and Ropemacs, I used Python's EasyInstall package manager. To use it, I downloaded and installed the setuptools package using the Windows install version. Once installed, at the command line, cd to their respective download locations and run the command
easy_install .
instead of the shell commands shown in the post.
Generally, I saved any *.el files in my ~\.emacs.d\plugins (e.g. in %USERPROFILE%\Application Data\.emacs.d\) and then updated my .emacs file to reference them as documented in the post.
Despite all this, on occasion, I've used DreamPie since it does have overall better auto-completion out of the box than my Emacs setup.

I'm spoiled by Intellisense too. The PyDev extensions for Eclipse offer a pretty good auto-complete substitute.

I find that PyDev + Eclipse can meet most of my needs. There is also PyCharm from the Intellij team. PyCharm has the added advantage of smooth integration with git.

I've been using PyScripter, an IDE for Windows, for a while now, and have found it very good. It has autocompletion among many other features. It's written in Delphi -- not that there's anything wrong with that -- it just bothers me a bit, though...

Take a look at Spyderlib, support most of the features including code completion

IMO, by far the easiest way to take advantage of the python tools available for emacs is to take advantage of the defaults that are all set up at:
https://github.com/gabrielelanaro/emacs-for-python
I actually took the time to get pymacs and ropemacs and python-mode all working independently before finding that little gem, and now I rely on it entirely for all my python based customizations. If you are new, I would definitely start there.

Using pydev with Eclipse on OSX

I setup PyDev with this path for the python interpreter
/System/Library/Frameworks/Python.framework/Versions/2.5/Python
since the one under /usr/bin were alias and Eclipse won't select it. I can run my python script now but cannot run the shell as an external tool. The message I get is
variable references empty selection ${resource_loc}
Same if I use {container_loc}
Any thoughts ?
Sunit

I installed the Python.org version as well, this is a must.
I finally got PyDev working in Eclipse by pointing the interpreter to:
/Library/Frameworks/Python.framework/Versions/2.6/bin/python
manually. If you don't do it manually (by using the Autoconfig) it seems to not find the right version.

Common practice seems to be to install an up-to-date Python 2.5 from python.org and use that instead of the system installation. I saw that recommended here and there when I got started on Mac OS X.
It installs under /Library (as opposed to /System/Library) so the system Python is intact. Pydev has /Library/Frameworks/Python.framework/Versions/2.5/Resources/Python.app/Contents/MacOS/Python as its configured Python interpreter and all is well.
Can't state for sure that your trouble is due only to using the system's Python installation; in any case this way I have no trouble. Also, this way when you fiddle with your development environment (install things in site-packages, upgrade Python), anything that uses the system Python is sure to be unaffected.

I know this is a ancient post... but, in case of some newbee like me to get the better answer.
I just using "Eclipse Marketplace" from the "Help" menu and search for keyword "python" or "PyDev" to get PyDev, and get it successfully installed.
AND, you should add PyDev to the top-right dock.
For the instance, my eclipse on my laptop's OSX is (Version: Indigo Service Release 2 Build id: 20120216-1857).
Have fun, folks! :)

I believe ${resource_loc} or ${container_loc} (without any argument) are based on the current selection in your workbench when you are launching your script.
So are you selecting the right resource when selecting that script through the "external tool" runner ?
At least, click on the project name before you run one of the external programs.
Note: it works with a selection in the Navigator or Package Explorers views (the latest might not be available in PyDev environment though)
