Unified script for Python2 and Python3

[mahirjain25]

At present, the web scraping scripts are separated for each Python version.

There is a need to create a single script, by examining points of difference between the two versions. This would mean exploring urllib2 and urllib for Python2 and Python3 respectively, and understanding each of the Python scripts currently implemented.

Further, appropriate changes to the documentation are needed once the above has been completed.
