Python programmers:
I'm having a couple of problems with python. First, surely there must be
a way to dump out of a program if some condition occurs, without having
to build all kinds of if's. Like:
def func():
stuff
if more_stuff:
return 0
else:
return 1
# main program
if func():
even_more_stuff
else:
how_the_hell_do_I_get_out
less_stuff
In C and the like, you can simply execute a return or exit anywhere in
main(), but not in python.
The second problem is sometimes related to the first. Apparently, when
you open a file, as in:
open(filename, 'r')
if the file doesn't exist, you get this hairy error message and the
interpreter just dumps out. I've never seen this kind of behavior
before. I'd expect something more like
if open(filename, 'r'):
do_stuff
else:
couldnt_open_the_file_stuff
But that doesn't work. The only way I can see around this is to surround
every call to open() with a try/except block. That's clunky to me.
Anyone know something I don't?
