How to store numerical lookup table in Python (with labels)
If you want to access the results by name, then you could use a python nested dictionary instead of ndarray, and serialize it in a .JSON text file using json module.
I have a scientific model which I am running in Python which produces a lookup table as output. That is, it produces a many-dimensional 'table' where each dimension is a parameter in the model and the value in each cell is the output of the model.
My question is how best to store this lookup table in Python. I am running the model in a loop over every possible parameter combination (using the fantastic itertools.product function), but I can't work out how best to store the outputs.
It would seem sensible to simply store the output as a ndarray, but I'd really like to be able to access the outputs based on the parameter values not just indices. For example, rather than accessing the values as table[16][5][17][14] I'd prefer to access them somehow using variable names/values, for example:
table[solar_z=45, solar_a=170, type=17, reflectance=0.37]
or something similar to that. It'd be brilliant if I were able to iterate over the values and get their parameter values back - that is, being able to find out that table[16]... corresponds to the outputs for solar_z = 45.
Is there a sensible way to do this in Python?
