Google News scraper to fetch links with similar stories
Instead of constructing the google_news_search_url with two string concatenations, use string formatting.
The other_news_sources_links line is very dense. Please split it up.
In addition to the defaults for all your args being None, you're calling all of your functions with keyword arguments, which seems unnecessary.
But before you fix that, consider why you need these 2 line functions in the first place. They don't seem to do anything complicated enough to warrant having to jump around in the code.
