How do I drop back to the python shell after exiting a script?

My python script has a couple of sys.exit() calls to terminate under certain conditions. To test it, I open up a python shell and run

exec(open('script.py').read())
. Whenever I hit a
sys.exit()
call, the script terminates, along with the python shell, which is irritating.

So I try to get creative and attempt to determine whether my script is run from the commandline or from the shell by examining the stack. Source : Detect if python script is run from an ipython shell, or run from the command line

def exit_now(exit_status):
os.system('pause')

if PythonShell: # how do I return to the python shell ?
???
else: # exit if we are running from the commandline
sys.exit(exit_status)

...

# check if this was run from inside a python shell
frames = len(inspect.stack())
if frames > 1:
PythonShell = True
else:
PythonShell = False

...

if condition1:
exit_now(1)

if condition2:
exit_now(2)

...

exit_now(0)

How about:

try:
    exec(open('script.py').read())
except SystemExit:
    pass
