I am new to Python deployment. I have a Python Web API made in Flask. Want guidance on how to publish the python code as web API so that Dot Net program can consume it and take benefit of Python / ML.
Apologies for such generic question, but any help or approach or documentations on the same would be grateful.
Thanks In Advance!!!..
As far as I know, if you want to deploy python application to the IIS. I suggest you could follow below steps:
1.Install Python on your server.
2.Install wfastcgi on your server.
3.Install the IIS(contol panel->Programs->Programs and Features->Turn Windows Features on or Off) with the CGI
4.Create a new IIS web app for the paython project folder.
5.Modify the handler mapping to add python handler. Notice: Modify the path based on your python and wfastcgi path
Run your application
More details, you could refer to below article:

I'm fairly new to Django so please excuse my ignorance.
I'm starting my first build of a web app on my remote web server. I am currently SSH'ing to the server and have started the Django project. I just launched the development server for the Django project, and it automatically serves at http://127.0.0.1:8000/.
My question is- what is the proper way to build a Django web app remotely on a server? Am I supposed to build the app on my computer and then transfer the project to my web server after it is complete? Or is there a way for me to access the development server without messing with the domains/ip addresses of the websites that are live on my web server?
Thanks!
This isn't really a Django specific question as the same basic methodology goes for any software development project.
Create different settings files for development and production. For Django this will involve setting the ALLOWED_HOSTS in your production settings as you mentioned as well as other settings. This checklist is helpful for this step. Use environment variables to hide secrets and set them in your development and production machines as appropriate.
Use a version control system such as git and push changes locally and then pull them onto your production server then run your Django server.
Do one better and setup a CI/CD pipeline to automate this
Yes, you're supposed to build working project on your computer :)
You probably cant efficiently write something good on the remote server.
Then you will probably create the git repository, for example on gitlab.
Then you will work on your computer building your project.
When you want to see it on the remote server, you will pull your project there.
It will be a little tricky for a first time to correctly deploy it, but it's not really that bad + there are a lot of good instructions out there, for ex:

I hope I correctly understood your question.
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)
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.

I am trying to test the new Spotify iOS SDK on a device, and this requires setting up a spotify_token_swap ruby file for oauth authentication.
I've never used ruby before and am a bit lost.
I also tried a python version of this file but also can't get it to work.
Does anyone have any advice on ruby script hosting, or any experience on working with the Spotify iOS SDK that could help?
Thanks
You can use this python service instead:
Download Google App engine here
Install the launcher
Go to chrismlarson's spotify-token-swap-gae and download the project, it will have everything you need.
In Google app engine launcher, Press add excisting project
Go Google app engines website and create a project, here you will get an app-id
in app.yaml , replace spotifyauth with the app-id
Press deploy
Done, you can now access it on the web at app-id.appspot.com/swap
Before I got this solution, I've spend hours in the jungle of Python and Ruby, Cheers!
There's another good alternative which you can deploy on Heroku:
https://github.com/bitstatic/spotify-swap-service-postgres
Just be mindful that you have to:
Probably edit config/environments.rb and change /mydb to /development
Run rake db:create
Run rake db:create_migration NAME=user_tokens
Edit db/migration/{dateandtime}_user_tokens.rb and replace it with:
class UserTokens < ActiveRecord::Migration
def up
create_table :user_tokens do |t|
t.string :username
t.string :refresh_token
end
end
def down
drop_table :user_tokens
end
end
Run rake db:migrate
Most of this is covered in the Readme, and it even includes a helpful guide on setting up Postgres on your localhost! Once the migrations are set up it's a simple git push heroku master.
Good luck!
ps. Let Spotify know that setting up a token swap server is a lot of work, and they can follow Facebook's example of having 60-day tokens, by commenting on this issue: https://github.com/spotify/ios-sdk/issues/159
I have downloaded and installed python on my PC. I am learning python at this moment so I am a beginner.
Is there anyway I could execute python scripts in localhost (Apache) and view them in a web browser as we do with PHP? I am executing the python scripts from CLI at this moment.
Although there are multiple solutions, I would take a look at mod_python. Unfortunately, in my experience it is not the easiest thing in the world to set up and requires making changes to httpd.conf, but this tutorial is helpful (and gives some examples).
Google App Engine SDK for Python includes a local web server application that simulates the App Engine environment. It allows for instant server script changes by just saving the file and refreshing the browser.
The development tutorial is here
Once you have your web site working locally, it is easy to deploy it live on Google's App Engine servers.
