My code is below.
This is always a tricky thing to go about. Nicely human-readable doesn't imply nicely machine readable. Sometimes a single space or a single tab between values/columns is more practical for a(nother) program to read, but not for humans. So I will work from the assummption that you want it human-readable only. In that case, have a careful read through the string formatting options: http://docs.python.org/library/stdtypes.html#string-formatting Before the two tables there, there's a point 4 which mention a minimum field width; that'd be something you could use. Eg: >>> print "|%20d|" % 10 | 10| >>> print "|%20.5f|" % 12.3456789 | 12.34568| >>> Hopefully that gets you on the way.
