index scipy.io.matlab.mio5_params.mat_struct with list

Question

I have many .mat files that I need to bring into python and do things with. I found a method to easily deal with the .mat files here. This works very well but now I would like to iterate over all the values. How do I do this?

wObs = 'path/to/matfile.mat'
mat = loadmat(wObs)
mat = mat['wObjs']

#function I wrote to get the field names of the .mat file. Returns a list of field names.
fields = mat_feildnames(wObs, 'wObjs') 

#now I want to itterate over the data and do things... 
for row in range(len(mat)):
    for field in fields:

        #field is string value.. how do I make this work?
        #this format if field is a valid field name will return what I want. 
        print(mat[row].field)


>>mat['wObjs'] 
   Returns:
   array([<scipy.io.matlab.mio5_params.mat_struct object at 0x7f0de3fe5e80>,

I re-read the linked to post and figured I'd try one of the lesser responses to see what it did.. it worked.. yay! Below is the answer to my above question.

import scipy.io as spio

vig=spio.loadmat(wObs,squeeze_me=True)
for field in fields:
    print(vig['wObjs'][field])

index scipy.io.matlab.mio5_params.mat_struct with list
