Python and JavaScript/AngularJS documentation on the one server?

The advantages of this approach include:
Consistent docstring syntax everywhere
Centralsied documentation server; find all your docs in one place
Search and jump-to-source from any documented function or class; in either language
Are there any modules integrating with Sphinx or similar; which generate+put your JavaScript and Python documentation in one place?

I am not sure if your question is about public documentation or in-house documentation of some of your projects.
For the former you want to see this: http://devdocs.io/
Also devdocs document scrapers are open source, so you should be able to use them for your own projects to build custom devdocs.io.

how can i use spellchecking in django (haystack with whoosh)?

I am working on a django website. I want to search from a lots of texts from django.models(texts is something like stackoverflow questions). I am doing search with Haystack+whoosh. It is very nice using it. Much better than django.object.filter(body_text__icontains="food")
So i would like to know whether i able to have Spelling Suggestions using whoosh or some other PUre python package available. i don't like solr(since it needs java, after every update i need to rebuild the index using java(solr))

Whoosh's documentation for version 2.4.1 indicates it does indeed have a pure-Python spelling suggestion module.

Python equivalents to Perl's URI::Find

In Python, are there any modules for extracting plain urls from a string like Perl's URI::Find does?
Thanks.

Here is a regex which can help you find the urls in text. There is no famous package in python which does uri::find in plain text. The sphinx documentation project however, includes a builder called linkcheck which finds all the links and checks for validity. You can check it's source too, but the linked regex is somewhat simpler.
If you simply care about http and https, the answer is here.

How to create an internationalized Google App Engine application

I would like to provide my Python GAE website in the user's own language, using only the tools available directly in App Engine. For that, I would like to use GNU gettext files (.po and .mo files).
Has someone successfully combined Python Google App Engine and gettext files? If so, could you please provide the steps you used?
I had started a discussion in GAE's Google group, but haven't been able to extract from it how I'd like to do it: I don't want to add external dependencies, like Babel (suggested in the discussion). I want to use plain vanilla Google App Engine, so no manual update of Django or this kind of stuff.
At first, I will start using the language sent by the browser, so no need to manually force the language by using cookies etc. However, I might add a language changing feature later, once the basic internationalization works.
As a background note to give you more details about what I'm trying to do, I would like to internationalize Issue Tracker Tracker, an open source application I've hosted on Launchpad. I plan to use Launchpad's translation platform (explaining why I'd like to use .mo files). You can have a look at the source code in it's Bazaar branch (sorry no link due to stackoverflow spam prevention limit for new users...)
Thanks for helping me advance on this project!

As my needs were simple, I used a simple hack instead of (unavailable) gettext. I created a file with string translations, translate.py. Approximately like this:
en={}
ru={}
en['default_site_title']=u"Site title in English"
ru['default_site_title']=u"Название сайта по-русски"
Then in the main code I defined a function which returns a dictionary with translations into the most suitable language from the list (the first one to have a translation is used or English):
import translate
def get_messages(languages=[]):
msgs=translate.en
for lang in languages:
if hasattr(translate,lang):
msgs=getattr(translate,lang)
break
return msgs
Usage:
msgs = get_messages(["it","ru","en"])
hi = msgs['hello_message'] % 'yourname'
I also defined a helper function which extracts a list of languages from Accept-Language header.
It's not the most flexible solution, but it doesn't have any external dependencies and works for me (in a toy project). I think translate.py may be generated automatically from gettext files.
In case you want to see more, my actual source is here.

You can use the Django internationalisation tool, like explained here.
They are also saying that there is no easy way to do this.
I hope that helps you :)

Where is Python used? I read about it a lot on Reddit

I have downloaded the Pyscripter and learning Python. But I have no Idea if it has any job value , especially in India. I am learning Python as a Hobby. But it would be comforting to know if Python programmers are in demand in India.

Everywhere. It's used extensively by google for one.
See list of python software for more info, and also who uses python on the web?

In many large companies it is a primary scripting language.
Google is using it along with Java and C++ and almost nothing else.
Also many web pages are built on top of python and Django.
Another place is game development. Many games have their engines written in C++ but all the logic in Python.
In other words it is one of the most valuable tools.
This might be of interest for you as well:
Is Python good for big software projects (not web based)?
Are there any good reasons why I should not use Python?
What did you use to teach yourself python?

It definitely has job value. For instance Google requires it. Have a look at Google openings in India:
Excellent programming skills in at
least one of the following languages:
C, C++, Java or Python (C++/Python
preferred)

Not sure about India, but you can get a decent overview of available Python jobs on the python.org jobs page here.

Try looking at Mark Pilgrim's excellent book "Dive Into Python" which is available for download under GNU Free Documentation License.
HTH

In 10 years of web development I've had 1 client have me write an email parsing app with it. Not that it doesn't get used, but I've seen Ruby/php/.net way more often in the wild.
Edit:
From the other posts if you plan on working at Google, it sounds like the language to learn - LOL!

It's juste one example but I know it is widely used in large scientific institutions with high tech machinery where non-programmers (typically physicists) need quick prototypes or tools to cover their data collection/processing needs. The easy-to access scripting language aspect clearly plays its role here. So I don't know about building a career out of that only but I'd definitely say that knowing Python is a very valuable asset on your resume, it'll strengthen your "smell of usefulness".

The google app engine lets you use python (or Java). I HIGHLY recommend that you check it out. If you want to have a FREE website with a database (actually a datastore but it works much like a database) using python, THIS IS IT. It scales up too. If you start to get enough traffic you would have to start paying for the usage it requires.

You could make your own python based site and run some ads. Voila, make some money. Also, I'm sure google could be impressed by some good python because I hear they use it for much of their own sites.
