带列表的索引scipy.io.matlab.mio5_params.mat_struct

Question

我有很多.mat文件，我需要把它们带到python中去做一些事情。我找到了一种简单的方法来处理here的.mat文件。这工作得很好，但现在我想迭代所有的值。我该怎么做呢？

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>,
   <scipy.io.matlab.mio5_params.mat_struct object at 0x7f0de3fe5eb8>,

我重新阅读了链接到帖子，并认为我可以尝试一个较小的回应，看看它的作用。它成功了..。耶！下面是我上面问题的答案。

import scipy.io as spio

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