I am trying to finish a personal project, which I describe its operation below.
My project consists of running a script (like a service) in the cloud.
I have on the one hand, a python script (created by me) which I want to host, and on the other hand a c++ script (not created by me), which I need to use from my python script, using boost-python.
My first way was to host my python script in pythonanywhere, but it doesn't work for me because the c++ script was designed for windows (it uses libraries only for the windows platform such as windows.h) and when compiling it ends in an error (pythonanywhere uses linux as base system).
So I would like someone to help me and tell me what is the correct way to do what I describe. I understand that it can be one of the following variants, but in some cases I am not entirely convinced that it can, or I do not know how to proceed.
Pay for a Virtual Desktop, and schedule the execution of my python script.
Use what is explained here.
Use a docket image with windows and host it somewhere.
Use Heroku
Note. My project needs/use a database.
Linux also supports C compilation. It's kernel is coded in C. Try compiling your code on linux with a tool like gcc, available on it.

I have a client for whom I have created a program that utilizes a variety of data and machine learning packages. The client would like for the program to be easily run without installing any type of python environment. Is this possible?
I am assuming the best bet would be to transform the .py file into a .exe file but am unsure of how to do this if I have packages that need to be installed before the program can be run.
Are there websites that exist that allow you to easily host complex .py files on them to be run by anyone that accesses the URL?
I think you are looking for "freezing", which package everything including the interpreter, libs and packages into a single executable file.
There are several tools for this purpose:
https://wiki.python.org/moin/Freeze
https://docs.python-guide.org/shipping/freezing/
I think the use of colaboratory that is cloud service provided by Google might be better. Your client who has to sign up for Google account can not only run the python program, but also utilize any major python packages on the cloud (of course, it's possible to install the necessary packages into the client's cloud space), without constructing the python environment on client's local PC. What's more, it's at free!
Background:
I am still new to Python so apologies if this is a naive question. I was originally looking to develop a tool for Windows with a GUI, however, reading around I get the impression that it may be simpler to have my compiled python code somehow 'wrapped' in simpleHTTPServer so users can interact via localhost (much like Jupyter notebook/labs).
Question:
Is there a standard/recommended way to have a compiled python program interface with the user via a localhost port in their web browser? I assume this is a fairly common approach and that a package may already even exist but I've not been able to find anything that gives guidance on how to tackle it.
Alternatively, is is feasible to somehow compile a Django development project to run on localhost?
Ideally, I want an executable file that users can run and their browser opens up at the localhost port required.
If you wish to quickly make a GUI based Python tool, you should consider using Django, a very straightforward framework for WebApps. It is very quick to learn and implement, and you shall very easily be able to integrate highly advanced functionalities too into your tool with ease.
When it comes to distribution of code, you can convert the entire Django App into a windows exe file for ease of distribution and use. There are many python packages that allow you to port python to windows executable files. I would recommend using PyInstaller. You may find this link useful: Recipe Executable From Django.
Alternatively, as someone suggested, you may use Docker, but that would be heavier in terms of space utilized, and will require the user to install the same.
Hope this helps!
I'm building some simple editors with Backbone.js, and I'm hoping to be able to distribute them as apps for users to edit content in a mostly client-side way (i.e., I don't want users to have to futz with setting up stuff like MySQL or Apache).
So I was imagining a scenario like:
User downloads a .zip file
In the resulting opened folder, the user clicks index.html
That opens in a browser
Backbone app starts, stores data in localStorage
The user can then export to CSV.
Believe it or not, that would solve my problem: I want to help users edit data in a browser and then get it back out in a familiar format (CSV can be loaded into Excel, for instance).
And I’d like to do this without forcing them to configure a server. It seems like this is almost possible in the HTML5 stack. However, in at least one browser (Chrome), this doesn't work, because I get errors like this one:
XMLHttpRequest cannot load file:///users/me/project/data/Appdata.json. Origin null is not allowed by Access-Control-Allow-Origin.
(Oddly enough, I don't get that error in Firefox, and the .js or .json files load fine.)
So at this point it seems to me that there's no way around having these users use something kind of local server to serve up the Backbone interface.
So, I'm trying to figure out how to build a distributable, cross-platform executable that will allow my users to start a Flask server. (I hope to build a REST backend to a Backbone.js app.)
Is this wishful thinking? I'm assuming I can get the people in question to install Python.
Is this doable? There seem to be many ways to package up Python programs, (pyinstaller? py2exe? ...) So I thought I would ask here in case someone might know of a solution for the stack I have in mind.
TIA!
You can use Anthony Gordon McMillan’s Pyinstaller or Tuininga’s cx_Freeze
Quoting the PyInstaller website:
Features
Packaging of Python programs into standard executables, that work on
computers without Python installed.
Multiplatform: works under
Windows (32-bit and 64-bit),
Linux (32-bit and 64-bit),
Mac OS X (32-bit only, 64-bit in git, see Features/MacOsCompatibility) and
experimentally Solaris and AIX (in git).
Multiversion: works under any version of Python from 2.2 up to 2.7.
My suggestion would be to create a thin service wrapper around your code. This will allow the server to run independently of your main codebase - also allowing the user to shut down the server directly (simply right clicking the service icon and selecting "Exit").
This SO answer should help you get started.
After reading your updated question, I think something like mongoose might be more suited to your task. It is an embeddable web server that is FLOSS and has python bindings. Flask might be overkill.
Not easily. On Windows, you'd have to include Python itself. Mac and Linux usually have Python installed, but you can't be sure of what version so it's often easier to bundle your specific Python for them as well. Then you'd have to include all the dependencies that you want to run with in your package or be able to install them with pip, easy_install, etc.
You can use py2app and py2exe. This won't be cross-platform as you'll still need to make a different version for each target OS. The only way to make it cross-platform is to bundle all versions and have some cross-platform code execute the appropriate version for that platform.
If you need databases like MySQL or even SQLite things get more complicated as you'll have to include those too.
I'm working on an embedded device that runs Linux on ARM7 with 64MB RAM and 64MB storage (12MB free). The device should be configured via web therefore it needs to run an embedded web server. Currently it's using Lighttpd and LUA, but I'm thinking about replacing LUA (or maybe even Lighttpd) with Python. The server will occasionally be accessed by one or two users for making changes to internal settings of the C program that is running in Linux. So the server load isn't really a lot. I also need it to be Open Source Software. Web.py seems to be small enough but I still need to compile Python which I haven't done before. So I'm wondering what are the system requirements of Python? LUA seems to do quite well for small embedded systems but I don't like its syntax for C-binding.
However, I couldn't find updated information about system requirements for embedding Python in such settings. This page from Michael Lauer seems to be old.
Any ideas? Suggestions? hints? links?
I'm working on this device using OpenWRT + Python:
http://wiki.openwrt.org/oldwiki/OpenWrtDocs/Hardware/Meraki/Mini
The first python run is veeeeeery slow but it are metacompiling all .pyc files, next it work well.
I'd like to get some code editing for a free software project done during some free time that I will have today at my university. There's just one small problem: We're almost entirely a windows environment (mostly thin clients at that) and the only source code editor installed is jGRASP.
So, I need a source code editor which is usable without installing anything (something browser, or Java Web Start based). I would use Notepad++, but I think downloading and running some unapproved exe may be in violation of our acceptable use policy, and it isn't that efficient of an editor for python anyway.
Any suggestions are appreciated.
The best webbased editor I know is Ace.
If you can't execute downloaded exes, this maybe mute, but SciTe is reasonably useable and does not require you to install anything - just download and run.
Putty and vim would be my solution (Requires a remote host running 'nix)
Putty is obviously a 3rd party binary, but a fairly common one.
I'm sure there are web based ssh clients to be had.
