I have written a python script that extracts data from flickr site, and dump as a python class object and YAML file.
I was planning to turn this into a website:
and a simple html front page that can send a request to the backend, triggers the python scripts running on the backend
the response will be parsed and render as a table on the html page.
Are there any suggestions for building this application? Any framework or technologies i should use? For example, i guess i should use ajax in the front end, how about the backend?
You can look on Django or Flask. As for me, Flask is much better for you, because it smallest and simplier. You can read about building Flask app here: http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world And about Django here: http://www.djangobook.com/en/2.0/index.html I used both for building applications with AJAX.
Please note that Django has better Python 3 support.
Also you can see on Bottle or something other. Try google if you'll dislike Django and Flask. For example, comparison of Python web frameworks: http://www.sixfeetup.com/blog/4-python-web-frameworks-compared
