Question

Is there a way I can, from within a Python program, run a C++ .exe and time how long it takes to return a value (and also be able to print to screen what that program’s return value is)? These programs are C++ console programs.

Answer 1

Something like

import subprocess
import datetime

t1 = datetime.datetime.now()
h = subprocess.Popen(...) # See subprocess module documentation for the args
h.communicate()
t2 = datetime.datetime.now()
print("Return Code: %d" % h.returncode)
print("Delta: %s" % (t2 - t1))

Should work.
