This is an artifact of entering in code manually in the shell, which
normally would have more cues to go on. In a script it would no that
these two statements were unrelated; in the interactive interpreter it
can't be sure so is waiting for a blank link to separate them. You can
tell this when the prompt is ... instead of >>>.

>>> try: f = open("nofile")
... except IOError: pass
... # note I hit a blank line here
>>> print "The exception just passed!"
The exception just passed!
