I have made a python program which does some text processing to whatever input I give and for now run I it simply by our terminal window(cmd). But now we want to make a simple web app which takes the input from user and then my application processes it and then the result is shown to user. Something like http://textanalysisonline.com/simple-text-summarizer.
As i am new to all this any help would be appreciated. thanks
I suggest looking into using Django - A framework for making python (web) applications.
I would look into downloading the python IDE PyCharm as it makes Django development quite easy and then look into some tutorials on how to make Django applications.
then I would install Django and then follow the tutorials (maybe start here) for figuring out how to add your script to a Django application. Happy coding!

I want to write a program using python as logic, because of the extensive libraries available in python suited for this project, and to develop the UI using react.
Is this at all possible, or is there a different method which is easier?
if you want to use react as a front end for a website, you could run python as the back end using something like flask or Django. Python can't be run in the browser, you'll need to run python on a server or run in locally on your machine if the project is just for you.
I've got a python script that I want to build a locally-hosted web gui app for, so I can use the modern styling and tools available to web apps.
The scripts I'm running take a while to process, and I want to update the web app with visual updates, or at least something akin to what the console sees when using print() in python.
My initial hosting efforts have been based on this tutorial, and I tried out the methods in this answer to try and get data to update in a streamed fashion, but the pages only showed once the entire script was finished.
I'm wondering whether web.py could help me?
Any guidance, or even the right terms to google would be appreciated. Thanks.

Update: I've been reading up on node.js (something I've failed to do for years..) and, please correct me if I'm wrong, but it seems like it could be the answer. I'm even considering re-writing my original functions into node.js given the existence of this serial comms library
In essence I want to run existing python scripts through a web browser, display the text and plots(if any) and also keeping the ability to run them through the command line.
I am wondering is there any toolkit that can help me with the development.Also it would be nice if the toolkit does or allows JavaScript based interactive plots.
Thanks!

WSGI is designed for just this purpose - it provides an interface for a web server to initiate python scripts.
You probably don't want to work with WSGI in the raw. Flask is a straightforward, simple framework you might use for this.
The details of how to actually build a WSGI web server are well beyond the scope of a stackoverflow answer - you can find plenty of tutorial docs on Flask's website.
I have developed a few python programs that I want to make available online.
I am new to web services, and I am not sure what I need to do in order to create a service where somebody makes a request to an URL (for example), and the URL triggers a Python program that displays something in the user's browser, or a set of inputs are given to the program via browser, and then python does whatver it is supposed to do.
I was playing with the google app engine, which runs fine with the tutorial, and was planning to use it becuase it looks easy, but the problem with GAE is that it does not work well (or does not work at all) with some libraries that I plan to use.
I guess what I am trying to do is some sort of API using my WebFaction account.
Can anybody point me in the right directions? What choices do I have in WebFaction? What are the easiest tools available?
Thank you very much for your help in advance.
Cheers
Well, your question is a little bit generic, but here are a few pointers/tips:
Webfaction allows you to install pretty much anything you want (you need to compile it / or ask the admins to install some CentOS package for you).
They provide some default Apache server with mod_wsgi, so you can run web2py, Django or any other wsgi frameworks.
Most popular Python web frameworks have available installers in Webfaction (web2py, django...), so I would recommend you to go with one of them.
I would also install supervisord to keep your service running after some reboot/crash/problem.
I would be glad to help you if you have any specific question...
I am trying to run Jumo open source platform ( https://github.com/jumoconnect/openjumo) on my local machine (Windows 7). I have Python and Django installed and it works - I can create new project without problems, but I am not sure how to set existing project and make it work.
I am not experienced with Python/Django, so first I need to know whether it is hard task or not. I guess it's much complicated then installing WordPress or Joomla, but does that require a lot of work in order to set it up?
Can someone write some kind of guide if it is not too complicated? Or if there is some tutorial that explains how to do that, that would be great.
Just to be clear, I am not trying to learn something in one day, just want to see if this first step in using this platform is too hard, and if it's not, I'd continue learning, because this is exactly what I need for one project.
I use Python 2.7 and Django 1.3.1
Thanks
This project has a lot of external requirements which are not listed anywhere and unless you are comfortable and familiar with django, I wouldn't recommend installing it. Here are some but not all of the requirements that you'll need running:
Celery and django-celery
RabbitMQ (a broker for Celery), or another broker but then you'll have to edit settings.py again.
memcached (this is optional, as you can use django's own session middleware for development), but if you simply download the code and try to run it, you'll run into an error since the default settings.py has the default middleware commented out.
grappelli
django-jenkins (not required, but again, unless you edit the default settings.py, you'll get errors).
django-tastypie
django-debug-toolbar
Data science toolkit server
as you may know Django is a powerful web framework and Python is a programming language, for python itself you need more than a few months to become some kind of expert.
it's very easy to start, but not that easy to learn the whole stuff. Django is one of the most or maybe the most powerful web frameworks (beside Ruby on Rails).
my advice to you:
learn python's basics (there's many books such as dive into python,
...)
learn Django basics (Django Book)
use Django on a Gnu/Linux (for example Ubuntu)
learning basics of Django can be done in a few weeks.
consider deploying a Django website is not that easy. you need to know a little about Apache web server.
www.djangoproject.com
note that in python (like other programming languages) you need to define working path. errors mentioned in question's comments usually caused by this.
also you should check Python installation path. sometimes these kinds of errors occurs when there is a project with the same name as yours in python installation path.
