You can't do that, just as you can't break out of a loop by executing a
break within a function that's called inside the loop. Python insists
that break only occurs inside a loop construct.
You will have use some construct like
while True:
try:
exec(your_code)
except SomeException:
break
then have your executed code raise the appropriate exception to break
out of the loop.
If you'll forgive me saying so you seem to be relatively new to
programming, and newcomers often make inappropriate use of "exec", which
should really only be a last resort.
If you explain the problem in a little more depth (i.e. say exactly what
it is you are trying to do) you might get more helpful suggestion.
