ipython has a %run command designed precisely to do this.  You can keep your
favorite editor open and work on your code.  You just need to save and type
into ipython 'run scriptname', to re-execute the code each time just as if
you'd typed it.  Note that ipython uses readline, so you just need to type 'r'
and hit the up-arrow key to retrieve the previous command starting with the
letter r.

Type 'run?' (without the quotes) into ipython to get the gory details on the run
command, or have a look at the manual here (scroll down to the %run part):

Feel free to ask further questions on the ipython list, I don't keep up with
c.l.py too well these days, unfortunately.
