Python pprint(): Can I format items in an array?

Question

I have a two dimensional array of numbers, something like

[[1, 123, 2], [22, 4567, 33], [0, 0, 0]]

That I would like to print in a debugging session. It would be useful for the columns to line up.

Is there a way to tell pprint to use a particular printing format for the numbers (e.g. '%4d')?

Answer 1

If you aren't set on pprint then,

>>> masterList = [[1, 123, 2], [22, 4567, 33], [0, 0, 0]]
>>> print "\n".join("\t".join(["{0:04d}".format(num) for num in subList]) for subList in masterList)
0001    0123    0002
0022    4567    0033
0000    0000    0000
>>> 

otherwise refer to Acorn's comment.
