Regex that would give certain words python

Question

I am looking for a regex that gives words starting with letters, numbers or underscore ('_'). It can only include dot ('.') between the words and not at the end and should remove all other special characters. e.g

WARC-_Target-URI: http://www.allchocolate.com/health/basics/

should give

WARC, _Target, URI, http, www.allchocolate.com, health, basics

Any sort of help will be appreciated.

Answer 1

Here you are:

from re import findall

print findall(r'\w[\w.]*\w', 'WARC-_Target-URI: http://www.allchocolate.com/health/basics/')

['WARC', '_Target', 'URI', 'http', 'www.allchocolate.com', 'health', 'basics']

Unlike the other solutions, this will work in any situation (not just the example that you posted).
