If I want something in say - a mograph effector to run once
can I make a global ?? without assigning a value (as it would zero each time the script ran if I did)
The correct syntax and logic would be really helpful and I'm unsure of both - pls
the sort of thing I was trying to do........have no idea how to do this correctly advice pls
if global ------called Flag_something_done---- not assigned : ????? Do the operation Flag_something_done = 1

But setting globals is IMHO not a good style. I prefer using mutable objects available from the global-scope.
data = type('', (), dict(is_done = False))() def main() : if not data.is_done: # make it done ... data.is_done = True

If you really want to make it dirty:
def main() : if not globals().get('is_done', False) : # make it done ... globals()['is_done'] = True

cheers Niklas
I prefer to keep things as correct as possible I like the idea behind the mutable object with global scope

Thanks for the info Niklas
And yes it works - but...
As far as the Python Effector is concerned it appears this method can't be used as the global is only set when the file is opened and first run
For the Effector it needs something that can process
'is this the same as the last past through'? if True - skip setting it
and its also unclear if the effector in Parameter mode is working differently from the effector in Full mode Can the same method be used for both
