My app is purely console based. I just don't want the console to lock

Thanks.
Which version of Python are you using? time.sleep(x) can be interrupted
in Python 2.6.
I'm able to be more precise: time.sleep() can be interrupted in any Python
version since 2.3.
To the OP: beware of any unqualified 'except' clauses; a block like this:
try:
...
except:
do_something_or_pass
may "swallow" the KeyboardInterrupt exception (generated by a Ctrl-C
press).
From Python 2.5 and up, the most generic exception clause should read
`except Exception: ...`
In previous versions, you had to explicitely re-raise KeyboardInterrupt
and SystemExit in any catch-all block:
try:
...
except (KeyboardInterrupt, SystemExit):
raise
except:
...
