newbie question-multidimensional arrays

[Doug Jordan]

How do you define and access multidimensional arrays in Python?   I am new
to python and come from a C and FORTRAN background and I am not sure how to
define an array without giving the contents of the array.  Any help will be
appreciated.   I would like to be able to read and manipulate
multidimensional arrays using a nested loop.  I cannot find anything in the
documentation to help me.
