Removing execfile from python3 has broken the good-ol python-mode of emacs.
Changing the line In python-mode.el in function py-execute-file changing the line (cmd (format "execfile(r'%s') # PYTHON-MODE\n" filename))) to (cmd (format "exec(open(r'%s').read()) # PYTHON-MODE\n" filename))) seems to solve the problem Since I am not quite upto the subtleties of what all has changed vis-a-vis exec/execfile, please inform me if this is ok
