FORTRAN like formatting

[Cyril BAZIN]

Hello,

I don't anderstand very well Fortran syntax, but want you say
something like that:

def toTable(n1, n2, n3):
    return "%20s%20s%20s"%tuple(["%.12f"%x for x in [n1, n2, n3]])


Example:
>>> import math
>>> toTable(math.pi, 10, 8.2323)
'      3.141592653590     10.000000000000      8.232300000000'

If it is not that, please could you give an example of input and
output of your code?

Cyril
