Hello,
The subject of this topic is a suggestion about the language and not the
programming paradigm/style.
Why should I repeat global if I can use the line separation character \
(like I mentioned on my 1st email) or parentheses as I suggested?
"global existing_graph, expected_duration # "in_sec" is unnecessary"
No it is not unnecessary unless sec is the only unit you use (in this
case we have several units of duration and thus it is necessary).
Best regards,
JM

This is an example from my one of my programs:
global existing_graph, expected_duration_in_sec, file_size, \
file_mtime, no_change_counter
I think you're already running into serious design concerns here. Why
are file_size and file_mtime global? Perhaps a better design would
involve a class, where this function would become a method, and those
globals become "self.file_size" and "self.file_mtime". Then you can
have a single global instance of that class for now, but if ever you
need two of them, it's trivially easy. You encapsulate all of this
global state into a coherent package.
But if you MUST use globals, I would split the lines according to purpose:
global existing_graph, expected_duration # "in_sec" is unnecessary
global file_size, file_mtime
global no_change_counter # also probably needs a new name
That way, you're unlikely to run into the 80-char limit.
