Editing Wikipedia using Pywikibot

Pywikibot is a python library that can be used to read and edit Wikimedia sites. Following is a very simple program that can be used to create a new page on a user space, if it doesn't exist.

import pywikibot

p = pywikibot.Page(pywikibot.Site(fam="wikipedia", code="en"), 'User:Jsamwrites/Sandbox/Test')
if p.exists() == False:
    p.text = "hello world! testing pywikibot" #Wikipedia text context
    p.save(summary="Editing wikipedia using pywikibot") #Summary of the changes
