What are my options when I want to find a good interpolation for a coordinate in an irregular grid of values?

Question

I have a list points and their values that cover an area like so:

#x, y, value
list  = [
(1.123, 1.232, 15),
(1.121, 2.323, 12),
(1.124, 3.451, 17),
(1.120, 4.593, 06),
(1.121, 5.638, 09),
(2.123, 1.232, 19),
(2.121, 2.323, 72),
(2.124, 3.451, 13),
(2.120, 4.593, 99),
(2.121, 5.638, 04), and so on...]

I want to write a function interpolateValueAtCoordinate(x, y) that gives me a good interpolation of a value at the specific coordinates.

What could I do?

if you've got SciPy available look at interp2D
