According to the Python documentation, instead of this:
execfile("./filename")
Use this:
exec(open("./filename").read())

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).

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

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.

If you save your python file (e.g. "your_file.py") in the same directory as python.exe, you can run it from the console with the command: >>>exec(open("your_file.py").read()) You can also write your file there with (e.g.) >>>newfile = open("your_file.py", "w") >>>newfile.write("print('hello world!')") >>>newfile.close() You can check to make sure it is there with >>>import os >>>os.listdir() You should get something like this: ['DLLs', 'Doc', 'include', 'Lib', 'libs', 'LICENSE.txt', 'NEWS.txt', 'python.exe', 'python3.dll', 'python36.dll', 'pythonw.exe', 'Scripts', 'tcl', 'Tools', 'vcruntime140.dll', 'your_file.py'] This is what you get when you run it: >>>exec(open("your_file.py").read()) hello world! ...

execfile — CASAdocs documentation
When execfile is used within the filename being evaluated, it is necessary to add globals( ) as the second argument to those execfile calls in order for the secondary script to know about the global variables of the calling script. For example, within a script ‘mainscript.py’, calls to another script ‘myscript.py’ should be written as execfile(‘myscript.py’, globals()).
