Much of my MR research is quite computationally expensive so there are many times that I have been sitting wondering how many times through a certain loop I have been.  Enter progressbar.  It is a nice small package which allows me to see, quite nicely, where I am in my loop.

Here is an example of what I typically do:

[cc lang="python"]

from progressbar import ProgressBar, Percentage, Bar, ETA

coords = array( numpy.nonzero( _data[-1] > thresh ) ).transpose()

pbar = ProgressBar(widgets=['Calc Offset Map ', Percentage(), Bar(), ETA()], maxval=coords.shape[0]).start()

for ii,coord in enumerate(coords):

# some big calculation here
pbar.update(ii)

pbar.finish()

[/cc]

This gives me a really nice, informative and pleasing text progressbar.
