You have many options:
I frequently use Konrad Hinsen's "Scientific" package
(http://dirac.cnrs-orleans.fr/programs/scientific.html). It make importing
files from user input or other packages like matlab easy and supports
several file formats. The simpliest is a basic white-space-delimitted text file
if you have a text file "arrayfile.txt" that looks like this:
# arrayfile.txt (lines beginning with '#' are ignored)
1 2 3
4 5 6
6 8 9
You can fire up python and read in your matrix like this:
>>> from Scientific.IO.ArrayIO import readArray
>>> A = readArray('arrayfile.txt')
>>> print A
[[1 2 3]
[4 5 6]
[6 8 9]]
