Thank you Dieter, I never thought it will be so difficult task, All I was thinking was that, I just do not know how it is done. I wonder how the code developers work in this case every time a function is modified one has to restart the console is a nightmare... Hope one day some solution will be evolved. with best regards, Sudheer >________________________________ > From: dieter <dieter@handshake.de> >To: python-list@python.org >Sent: Monday, 19 August 2013 11:48 AM >Subject: Re: refresing the edited python function > > >Sudheer Joseph <sudheer.joseph@yahoo.com> writes: > >> I have been using ipython and ipython with qtconsole and working on a code with functions.
