If you want to DIY, have a look at string formatting (ie: the % operator).
I don't quite understand your example, so here's an (untested) example
of my own -- printing a list of strings in a table of 3 columns:
input = [ ... ] # list of strings
WIDTH = 3 # columns in the table
# split input up into tuples, ie: first 3, then next 3, then next 3, etc.
rows = [input[WIDTH*i:WIDTH*i+WIDTH] for i in range(len(input)//WIDTH + 1)]
# get max width of each column
widths = [max([row[i] for row in rows]) for i in range(WIDTH)]
for row in rows:
for i, s in enumerate(row):
print '%*s' % (widths[i], s),
print
The idea is to figure out what goes on each row of the table, then
calculate the maximum width of each column. Then
'%*s' % (w, s)
will be the string s, padded to width w.
(I always forget whether it gets padded on the left or on the right,
but you can always reverse it by adding a -: '%-*s' )
