Setting 'interactive=True' in .matplotlibrc

IDLE           #os.environ['PYTHONINSPECT'] = '1'        -> fail
IDLE -n        #os.environ['PYTHONINSPECT'] = '1'        -> fail
IDLE           os.environ['PYTHONINSPECT'] = '1'         -> fail
IDLE -n        os.environ['PYTHONINSPECT'] = '1'         -> success

So that's good. However, notice that also

setting 'interactive=False'

IDLE           os.environ['PYTHONINSPECT'] = '1'

seems to work! (Which is what I wanted initially and what didn't work.)


So from my naive perspective the line "environ['PYTHONINSPECT'] = '1'  " 
should not be commented.

Thanks for you help -- hope this is useful,
