Configuring Azure for Django/Python 3 - python

I had a Django project that uses python 3.2+. Having been through a couple Azure classes I wanted to deploy my Django application through Windows Azure. I got the web site synced through my Git Repository, and following the advice of the MSDN forums, added the python 33 runtime in a folder called /PythonCore/ and added WSCGI.py to the scripts folder within there.
My website can''t find the CGI interface and likewise is failing to process HTTP requests. I know something must be wrong in my configuration, but I havn't a clue as to what. I was wondering if anyone might know what my error is.
WEBSITE_NODE_DEFAULT_VERSION 0.10.5
DJANGO_SETTINGS_MODULE DjangoApplication.settings
PYTHONPATH D:\home\site\wwwroot\DjangoApplication;
WSGI_HANDLER django.core.handlers.wsgi.WSGIHandler
Handler Mappings
* D:\home\site\wwwroot\PythonCore\python.exe D:\home\site\wwwroot\PythonCore\scripts\wfastcgi.py
Please let me know if any additional information is needed or you have an idea what I can try.

Azure Web Sites w Django currently requires Python version 2.7. Please see this:

Need advice on how to incorporate Python into an Azure, specifically an ASP.NET web application environment

Need advice on how to incorporate Python into an Azure ASP.NET web application environment. Please excuse this question but I am new to Azure and I'm not clear on how to proceed. Every option that I look into looks promising but they all seem to have their own issues. Below is a more thorough explanation but the deal is that I have an Azure account with all kinds of goodies, a full fledged ASP.NET (C#) web app running via App Service, I am new to Azure (but not Python), and I'm hoping to add Python functionality to this whole setup. In short:
I want to add Python to this setup mainly to run scheduled jobs and also to trigger Python code from ASP.NET web form submissions
ideally I want a solution that resembles a non-cloud setup. I know this sounds silly but I'm finding the cloud/Azure functionality to be nuanced and not straightforward. I want a place to put a bunch of Python scripts, run, edit, schedule and trigger them from ASP.NET
for example: I created a WebJob that runs manually and from the documentation it wasn't clear how it should be called. I just figured out that you need to POST with Basic Auth (and the credentials provided).
!Also, Azure CMD does NOT like files with 'underscore _' in them! You cannot submit a Web Job with a py file with an underscore nor can you write output with a file with an underscore
!Also, I don't see an option for this Web Job to run Python 3.6.4 (which I installed via extension). Right now it is using 2.7.15...
!Also, CRON expression in Azure has six *, not five plus a command. Again, more weird stuff to worry about
I tried these instructions but the updates to the web page's Web.config file breaks the ASP.NET web pages
ideally the most cost effective option
Any info is greatly appreciated
MORE DETAILED EXPLANATION
Currently I have an ASP.NET site running via Azure App Service and I would like to add Python scripts and possibly Flask/Rest functionality. Note that I am not expecting to serve any content via Python and will largely be running Python scripts either on a scheduled basis or call them from ASP.NET. As a matter of fact, and this is an important point, I'm hoping to have ASP.NET trigger/run a Python script when a web form is submitted. I realize that I could get a similar effect if I make a web call to a Rest api that is running Python. In any event, I can't tell if I should:
add a Python extension to the current App Service running the web page (I tried this) OR
I did install Python 3.6.4 and some packages via pip
These instructions were useful, however the updates to the web page's Web.config file breaks the ASP.NET web pages
set up a VM that will have all of the Python code (but how can I have the .NET web page(s) call the Python in the VM?) OR
use Azure functions (I'm completely new to this and must admit that I prefer to have my old school Python environment instead although I see the benefit of using functions. But how do you deal with logging and debugging?)
or what about a custom windows container (Docker)?
This requires installing VS Code and that is OK but I'm looking for a solution that another user can get into with as few interruptions as possible
The idea is to ramp up the use of Python although, like I said, I don't expect Python to be serving any of the web content. It will be used to run in the background and to run scheduled jobs. What is the most robust and hopefully easiest way to add Python functionality to Azure (most importantly in a way to be able to trigger/use Python from an App Service running .NET?)? I've searched online and stack overflow so far with interesting finds but nothing to my liking.
For example, the following link discusses how to schedule WebJobs. I just created a manual one and when I called the webhook I got the message: "No route registered for '/api/triggeredwebjobs/TestPython/run'" How to schedule python web jobs on azure
The Docker method looks very promising, however, I'm looking for a simple solution as there is another person who will be involved in all of this and he's busy with other projects
Thank you very much!
I found a solution, though I'm open to more info. Like I mentioned in my post, I used the 'add extension' tool to add Python 3.6.4 to my Azure (installed in D:\home\python364x64).
Then I installed a bunch of packages via pip, these installed into D:\home\python364x64\Lib\site-packages.
I created a Python folder in webpages\Python where I put my scripts.
Finally, in ASP.NET I used the Diagnostics.Process call to run my code in ~\webpages\Python\somecode_2.py
The main issue is that Azure came with Python 2.7.15 installed. And for some reason when my Python code got executed it was using 3.4 (where that version came from beats me). So for each script, I had to create an _2.py version where I simply did the following in order to call the original script via Python 3.6.4. Looks a little nasty but it works. So like I said, I would welcome more info for ways to do this better...

import os<br>
os.system("D:\\home\python364x64\python.exe SomePython.py {0}".format(add arguments here)

what is .travis.yml file in python flask openshift application?

I'm new using python on openshift and I follow this tutorial to learn more about it https://developers.openshift.com/en/python-flask.html, then there is a thing that I can't find info in openshift docs or https://developers.openshift.com/en/python-flask.html
I suspect is defining the execution order of https://developers.openshift.com/en/python-repository-layout.html
Am I right or I missing something else?
It is used to automatically deploy your application.

Can't run coursebuilder in google app engine

It is really weird that after clicking run button, it does nothing and also no log and show a clock sign on the first column.
It works normally before. However, after I messed up my python environment, the google coursebuilder can't run web application. That's my guessing. When I run which python.it only shows:
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
These let me feel like I have no way to solve it!Are there anyone who came across this problem before? Any ideas or suggestions?
Updated: I follow suggestions to use command line to run web application on GAE. It reminds me here:
Update: The error message shows that GAE can't get the allocated port and domain. The reason why it happens is that when I use command line to run the web application, I also open GAE GUI to run a web app with the same port number.
So the way to solve it is to close the GAE GUI and free the port. Or we also could designate another kind of port number with command line.(--port=XXXX and --admin_port=YYYY). Or take a look at the doc:
Again thanks for the help of Mihail R!
The OP had multiple issues with GAE setup which were resolved by simply reinstalling the GAE Launcher and making sure the app was first copied into Applications from the .dmg file, then ran from the Applications instead of from inside the .dmg file, and appropriate permissions were suppose to be given so that GAE Launcher created the symlinks it needed to work properly.
More instructions on proper GAE SDK installation can be found here: https://cloud.google.com/appengine/downloads after clicking on the needed SDK and then the OS the SDK will be installed on.

What packaging option are available for python/django

I am starting on developing a django application on a shared webhosting server(alwaysdata.com).
I would like to understand what are the packaing options available to package a django application (preferably in compiled form)
I would like to setup the source code repository on my system and build using the python packaging and deploy the package on alwaysdata.com.
I would like the option of not having to share the source code on alwaysdata.com.
Looking at pip , I am not able to find this option.
EDIT
A few more clarification: I would need the ability to not share the sourcecode since it contains the "API secret key" which I would not want to compromise. The more I look into it , the more i believe that there is no way for me to distribute binary only distribution.
I've found fabric to be a pretty nice tool for deploying Django projects. To compile your python code you can use compileall:
python -m compileall <dir>
How is this API key used? Is it a google maps api? Is it provided in scripts that go to the browser? If so, it's already out in the open, anyone using your site will see it, so you're trying to provide a $100 lock for a $0.01 piece of information. If it's a google maps api, it's not secured by keeping it hidden, but rather it's tied to a domain/directory (IIRC).
Can you share a little more what the API key is and is for, then maybe we can help you find a better solution to keep it secure.
Do you think you have to share your source code if you host your application on a 'shared hosting' provider? That's not the case. Your source code should still be private to you but the administrators of your hosting provider can get it too. Other normal Joe Users of the service shouldn't have access to your source code, or your database too. If they do, then get another shared hosting provider!

Deploying Django on an apache server

I am new to web development. So be gentle. AND thanks in advance.
I am developing on windows env. and deploying on a linux server w/ Python 2.6.2 installed.
Running apache2.2 as Virtual Host, and I am using mod_wsgi. I plan to serve media files from the same Virtual Host.
I have a django site and I am now ready to deploy. I am stuck, and every site I go to seems to be outdated/incomplete/overmyhead.
https://docs.djangoproject.com/en/1.3/howto/deployment/modwsgi/
http://www.djangobook.com/en/2.0/chapter12/
...only 2 links as for the newbness
The top link seems to be what I need yet I am still confused on these things:
What does the file structure look like on the server
I cannot change/edit server files myself, I rely on the dba for that
I have django.wsgi, and django.wsgi~, where do those go?
Where do I put my project in relation to those wsgi files?
The httpd.conf file is something that the server has on it? or do I create another?
Do I need to put django in any way shape or form on the server? If so where? And what about the packages like registration, defaults?
Again sorry for the newbness, I have been banging my head for 2 weeks on this.
Any help/links will be greatly appreciated unless they link me to the django-docs. I have read those...A LOT! thanks
Also go read:
http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango
and watch:
http://code.google.com/p/modwsgi/wiki/WhereToGetHelp?tm=6#Conference_Presentations
The latter includes Django examples and talks a bit about locations, permissions etc.
The first of these is even linked to in the document in the Django documentation.
It doesn't matter where the files go. They just have to be readable/executable by the user that the web server is running under.
I don't know what you mean by django.wsgi~, that sounds like a backup file created by your editor - you don't need that.
Yes the httpd.conf is the configuration file for Apache. Some distributions (eg Debian and Ubuntu) split this up into separate files for each site that the server runs. If your administrator is the only one who can edit files, he will know about this already.
Yes, you need Django, and any third-party packages.

An easier option for you while you are learning this is not to really have to many expenses.
I could also suggest you take a look at Heroku - allows you to easily deploy your applications in minutes.
Up until recently they only supported RoR and they have brought in support for Django and Python - they have some really well documented tutorials as well.
I hope this helps
Heroku Django / Python tutorial
I have written up an simple deployment guide for django applications it can be found here. It goes all the way from project setup and deployment. I also have references setup. I honestly believe it answers all your questions, I would give it a look.
Goodluck.
