I'm wondering is that possible to control lights connected to Enttec Open DMX USB via Python shell. If it is, how to?
The Open Lighting Project (formerly known as opendmx) provides a Python API, as part of their Open Lighting Architecture (OLA), for use the OpenDMX USB on OSX and Linux. If you're on Windows then I've not found anything apart from the code from Enttec's website which uses the FTD2XX.DLL libraries.
However it should be noted that one cannot use normal serial based libraries (pyserial etc). Basically OLA either needs to use a special kernel module on Linux, or use the generic FTDI non-serial kernel driver in combination with libftdi on Mac or Linux - for details see their device specific page. There is now pre-built support for Raspberry Pi's on the OLA website.
The communication and protocols used are completely different from Enttec Pro range (which one can just control using simple serial commands with something like pyserial, though OLA also talks to them too).
I know this is quite an old post, however DmxPy has worked very well for me the last few months. It only works for Python 2 but I know there's some Python 3 ports out there.
It's stupid simple to use. I personally use it in my companies quality control software. While it only work for DMX (not RDM) I think it's much easier to use than OLA's Python Wrapper. It works flawlessly with our ENTTEC as well!
UPDATE: Here's my Python 3 port: https://github.com/trevordavies095/DmxPy
I had the exact same problem, so I wrote a simple python programm for all those that are running windows; have a look: https://github.com/Coronon/PyOpenDmxUsb
It uses a C# Server (Because their C# interface was the only one that worked for me) and a Python Client and is super easy to use.
It is compatible with the non pro version too. (The Pro Version is way easier to use and I would use the AcceptedAnswer instead [But the normal one isnt supported])
Edit: This may be 'advertisement' but my project is Open-Source and super easy to use, so I believe this can be useful to others :)

I am looking to connect to a car wirelessly using socketCAN protocol on MacOS using the module python-can on python3. I don't know how to install the socketCAN protocol on MacOS. Pls help.
This cat managed to get it basically working:
socketcanx
I have compiled it on my hackintosh (running Mojave) and it works from the terminal. I have not played around with it more than that, as it was just easier to use Liunx in a VM or docker or one of my Linux machines. When compiled, I was able to use all of my makeshift CAN devices and a USB2CAN device without issue. I am sure with some work, it can be used with Python-CAN, though you would need to write your own interface module for Python-CAN. As far as I can tell, it should work more or less the same, though the code is old (4 years since last update).
As stated in the accepted answer, you can use a native CAN device that is compatible with macOS and as long as it's compatible with Python-CAN, then you are good to go (or if it works on mac and not compatible, you can create and interface for the device and submit a pull-request on github for Python-CAN).
SocketCAN is implemented only for the Linux kernel. So it is not available on other operating systems. But as long as your CAN adapter is supported by python-can, you don't need SocketCAN.
Short version:
Is it possible to create a standalone program that can be distributed to computers that don't have python installed, which writes a python script during runtime and executes it during or shortly after?
Long version:
A project I've been wanting to do for a while is to create a visual programming interface, that lets people use Machine Learning without needing to know python/keras/numpy syntax. Programs like lobe or rapidminer already do this, but they are all bound to their own interfaces and servers. What i would like to do is create a program that:
anyone can use without needing python/anaconda installed
allow the user to create visual scripts like in scratch or google-blocs
generates python code behind the scenes containing keras or tf code
is able to execute the script
is able to show the code to the user for:
educational purposes
allowing the user to use it as a base for a more complex program
Since the generation part would just need to create a text file almost any interface and language like python/java using Qt or C# / javascript using Unity, would qualify. I think that should definitely be doable, probably just very long, but that is not my largest concern.
The problem:
I have tried to search everywhere on the internet about things like standalone python programs which led me to for instance py2exe. Those kind of python-to-exe's work great, but they all require the script to be compiled on a machine containing a python environment. In my case i want to be able to generate a python script on the user's PC, and run it directly after from there.
The alternative
If this isn't possible i might just create the whole AI part myself, not using python nor libraries like keras or tensorflow, but in a unity game for instance. The downside to this would be that it exists already(like rapidminer), it would be less optimized/versatile/customizable and doesn't show what the "real" machine learning script would look.
If there are any other alternatives i would be happy to hear them
PS.
I have mostly Python & Keras, moderate Java and little Unity3D or web JS experience
I'm using Windows with anaconda
Distributing to linux/mac would be nice, but not required
maybe you should check the Orange Data Mining software, it's written in python and it has the same purpose as your project (https://orange.biolab.si/). On the other hand, some time ago I tried to compile my app that contains machine learning libraries but to date, I have not been able to achieve it. Instead, what I use is the WINPYTHON project, this is a portable Anaconda software that allows you to run projects on any PC without the need to install anything (https://winpython.github.io/).
Yes, it is possible!
I had the same requirement, so I wrote my visual programming language and IDE...
...that could generate an almost python-like script, and which is compiled natively inside the app, without the use of any external compilers or libraries.
My target architecture was mobile devices, but it also works on browsers via the unity plugin.
...and yes, that's correct, it runs natively on your phone or tablet in a simulated sandbox, with its own built-in IDE.
It's written in C#, and implemented in Unity3d

I'm using a Raspberry Pi 3 to communicate with a GSM module over the GPIO pins. The operating system on the Pi is Raspbian Stretch. It has Python 2.7 installed. The standard way to communicate over the GPIO is using the serial library in Python which is pre-installed. I'm just trying to find the documentation for this library and can't find it anywhere.
Where is it?
I've tried googling for it and it only turns up a library called pyserial and examples of people using and trying to use the serial library but no documentation for it in sight.
I think the library serial is a bit too new, and since it has been developed by one single person, it might take time to get some documentation. What you can do is to have a quick overview of the project and its source code: https://bitbucket.org/davebelais/serial
I turns out it's at
https://pythonhosted.org/pyserial/
which is where you end up when you're googling, but I naturally ignored it assuming that the name of the library would be whatever you write in the import statement. Clearly this doesn't hold for python.
I'm trying to write a quick and dirty little program to poll a WASP-B ANT+ to wifi gateway on windows, using python (the language I'm most familiar with). The WASP-B device has an unpublished UDP protocol that is mixed up with NDA's and so forth, but they have a published .NET library for win32 programming. So ... I googled around a bit and found IronPython and python.NET. If I understand correctly, IronPython is a .NET application or something? Not really what I'm after, I just want to be able to use the "stuff" in the WASP-B's .NET library from within a python program, so I think python.NET is the better option for me.
As far as I can tell, python.NET isn't all that active though - does anyone here know if it's live, if it'll work with current (3.x) python on Windows and if I'm on the right track?
On sourceforge, python.NET hasn't been touched since Jan 2013 :
http://sourceforge.net/projects/pythonnet/
The WASP, for anyone interested :

If you're looking for a Python variant that plays very well with .NET, then I highly suggest Iron Python: http://ironpython.net/ it is an open-source variant of Python that was integrated with the .NET framework, allowing it to behave similarly to one of the .NET-friendly languages.
As far as being active, the last update was made on May 25, 2014, which is pretty recent. The updates are not frequent, but for the most part there is no need for them, beyond some improvements and fixes. I would suggest giving it a try and see if it works for you. It's hard to answer a question of something being the right thing for the job unless youn give it a try.
IronPython works wells within .NET environments (calling .NET assemblies). If you stay within .NET framework then IronPython is recommended. Note Python 3 port is in progress and the syntax is not supported yet (Jan 2015).
But CPython (main Python implementation) works well with Python.NET both for extending and embedding. The reason for using CPython with Python.NET is if you need libraries that call Python C-API (not supported by IronPython), like Numpy, Scipy, Pandas, Cython, Matplotlib, etc. Python 3 port is here:

I'm starting developing to Bada platform. But C++ isn't my favorite language. So, is there any way to run Python on Bada?
Update: For Android there is a scpripting layer (SL4A), and it's make possible to quickly prototype applications for android on the device itself using high level scripting languages. Is there nothing like that for Bada?
Thanks.
Is it possible to use Python on Bada ?
In simple words No.
Applications must be written originally in C/C++/Objective-C . No third-party APIs, development tools or “code translators (e.g. from Python to C++) are allowed.
You can’t even compile very classic library such as OpenSSL or libCurl. The support of the STL is not complete
The Bada platform APIs are a lot more closed than Apple’s ones.
You can try with boost::python, but Im not sure if it will work in a proper way.
