[SciPy-user] How Do I Interpolate a Grid of Data

Hello,

         I am new to python and scipy.  Lets say I have a file called
grid.txt that looks like this
( x, y, f(x,y)):

1   1   0.6
3   1   0.8
7   1   2.3
1   3   0.3
3   3   1.5
7   3  1.3
1   7   2.6
3   7   2.8
7   7   1.3

How would I, using scipy, interpolate this so I get a value at any point on
a new grid [0,10]x[0,10]?   IE,  I would like to take the above
information and create some NXN array f so that I could say print
f[1][2] or print f[9][10] say, and it would give me the interpolated
value at that point.  Thanks.

                         Joseph Smidt
