My kind of programming language! See http://www.python.org/doc/humor/#bad-habits. Anyway, that translates, more or less, as follows. Note that I'm modeling the Fortran 2-dimensional array as a dictionary keyed by (k, l) tuples. That's easy an convenient, but conceptually a poor fit and not terribly efficient. If efficiency is an issue (i.e. much larger values of (k, l), you probably want to be looking at numpy. Also, "in" is a keyword in python, so I changed that to "value". There's probably cleaner ways to do this. I did a pretty literal transliteration. matrix = {} value = 0 for k in range(1, 6): for l in range(1, 6): value += 1 matrix[(k, l)] = value for i in range(1, 6): print ",".join("%5d" % matrix[(i, j)] for j in range(1, 6)) This prints: 1, 2, 3, 4, 5 6, 7, 8, 9, 10 11, 12, 13, 14, 15 16, 17, 18, 19, 20 21, 22, 23, 24, 25 -- http://mail.python.org/mailman/listinfo/python-list
