You are just supposed to read the file and exec the code yourself. 2to3 currently replaces this:
execfile("somefile.py", global_vars, local_vars)
With this:
with open("somefile.py") as f:
code = compile(f.read(), "somefile.py", 'exec')
exec(code, global_vars, local_vars)
(The compile call isn't strictly needed, but it associates the filename with the code object, making debugging a little easier).

October 17, 2005 - That is the code that execfile()'s the file and then inits the class that was inside. It's probably a messy way to do it but Python doens't have variable variables like PHP and it's the best I could come up with on short notice. If I have an import statement inside the file that I pass to ...

GitHub - projg2/python-exec: Wrapper for multi-implementation install of Python scripts and executables
In other words, to wrap /usr/bin/foo, you would: 1. install the real script into /usr/lib/python-exec/pythonX.Y/foo, 2. symlink /usr/bin/foo -> /usr/lib/python-exec/python-exec2. Afterwards, whenever the wrapper script is run python-exec will try to determine the most preferred Python implementation supported by the script and run the appropriate variant.

Actually, wouldn't we want to do this?
import sys
sys.argv = ['abc.py','arg1', 'arg2']
execfile('abc.py')
2 of 13

try this:
import sys
sys.argv = ['arg1', 'arg2']
execfile('abc.py')
Note that when abc.py finishes, control will be returned to the calling program. Note too that abc.py can call quit() if indeed finished.
