It's a placeholder for formatting. It represents a string.

" %s link.get" % ('href')

is equivalent to

" " + 'href' + " link.get"

The placeholders can make things more readable, without cluttering the text with quotes and +. Though in this case, there is no variable, so it is simply

" href link.get"

However, .format() is preferred to % formatting nowadays, like

" {} link.get".format('href')
