pretty easy progress indicator

stdout_progress.py

# this works just fine w/ multiprocess...
# now with more flushing

import sys
import time

sys.stdout.write("This is running")
sys.stdout.flush()
for i in range(5):
    sys.stdout.write(".")
    sys.stdout.flush()
    time.sleep(0.1)
sys.stdout.write("\nThis is running2")
sys.stdout.flush()
for i in range(10):
    sys.stdout.write(".")
    sys.stdout.flush()
    time.sleep(0.1)
print ""

Cool. I ended up embedding progressbar.py in PyMC (http://code.google.com/p/python-progressbar/), because I'm lazy.

The biggest problem with progressbar, in certain cases, is that i have to have some idea of the number of whatever it is that i'm processing. In the case of a 5 GB input file, computing the number of lines in the file is super slow (i,e. assuming we're processing line-by-line). I prefer the above in this case, because i really just want to know that something is still going on and get a rough visual indicator (e.g. one dot every 10k lines) of progress. Of course, there are any number of other, approximate, workarounds.

Otherwise, progressbar is actually "prettier".

edit: speelling

I use progressbar when I need to know the actual progress. otherwise, I sometimes use a spin cursor.

then of course, flush a dot is always most effective.

ooh, i like this spin cursor - much more fancy-pants than my lowly dot flusher ; )
