code:-
# Internal -- finish processing of end tag
def finish_endtag(self, tag):
if not tag: # <---- i am confused about this
found = len(self.stack) - 1
if found < 0:
self.unknown_endtag(tag) # <---- and this
return
I am a little confused as to what is intended by " if not tag: "
does it mean
if tag == None or tag == "": # ?
tag here is suppose to be a string.
so the only way it will be True is when its either None or its "", then
we are essentially passing None or "" to self.unknown_endtag(tag) ??
thank you in advance.
