How to avoid leaving extra blank lines when removing templates? - pywikibot

21 Mar 2023

I've got some code which is essentially:

...
          wikicode = mwp.parse(self.page.get())
         for node in wikicode.filter_templates(recursive=False, matches=title):
             wikicode.remove(node)
         self.page.text = str(wikicode)
         self.page.save() 

which works, but it leaves an extra blank line behind where the template used to be.  This
is intended to be run on [[:en:Template talk:Did you know/Approved]], i.e. one template
per line.

What's the best way to get rid of the blank lines?  I'm trying to avoid just
running a regex replacement on the raw text because that's fragile, but maybe theres
really no good alternative here?
