Stopping Execution

[James Colannino]

Hey everyone. I remember from my C programming that I can either use
the exit() or return() functions to end execution of the main code
block. My question is, is there a way for me to do this in Python? I
know there has to be, but I can't for the life of me figure out what it
is. The reason I ask is that I need to conditionally end a script I'm
writing at various places. Thanks in advance.

James

Which is Fredrik's way of telling you you need to *call* sys.exit and
not just reference it (works in Perl, which assumes you want to call it,
but in Python "explicit is better than implicit").

$ more test.py
import sys
print "should get here"
sys.exit()
print "should never get here"

$ python test.py
should get here
