So these days I’m often using:
mpirun -np 8 xterm -e gdb -ex run --args python script.py

]]> Comment on Simple Timer using Python’s With Statement by Aaron Meurer http://bfroehle.com/2011/07/simple-timer/#comment-1138 Aaron Meurer Sat, 22 Sep 2012 01:24:16 +0000 http://bfroehle.com/?p=46#comment-1138 I think a better characterization of a with statement is as a try, finally block. So the open example is actually the same as (I hope WordPress doesn’t kill my indentation)

try:
f = open(‘/tmp/workfile’, ‘r’)
read_data = f.read()
finally:
f.close()

The important thing being that the f.close() is *always* run, even if some unexpected exception is raised. You can even call “return” and it will still be called. It’s the same with __exit__ in a context manager.

And by the way, if you want to use the with statement in Python 2.5, you have to add “from __future__ import with_statement” to the top of the file (or type that out if you’re running interactively).
