自动解析numpy recarray

Question

Hi I have some binary Files created in IDL (Interactive Data Language) which can be read through scipy using

scipy.io.readsav

In particular I used it as follow

data = scipy.io.readsav("input.sav", python_dict=True)

so that the output is a standard python dictionary. In particular the output I can access the numpy.recarray which is stored in the dictionary

du = data.keys()
duV = data[du[0]]

so duV now is a recarray. I don't know a priori the variables and the names which are stored in the recarray. I can access the names of the variables as

names = duV.dtype.names

Now suppose that names is equal to

('V', 'T', 'THETA', 'ERR')

I would like to find an automatically procedure to read all the variables with the corresponding names, ie something which automatically do as

v = duV.field('V')
t = duV.field('T')

ect. ect. So I would like to create variables which are named as the names of the recarray

Answer 1

If you want to put all the fields in to global variables, you can do:

for name in duV.dtype.names:
    globals()[name.lower()] = duV.field(name)
