How to open a mat file in python

I was trying to open a mat file in python but my attempts did fail. Here is my code

from  scipy import *
from  pylab import *


save('rfdata.mat')
import scipy.io as sio
mat = scipy.io.loadmat('rfdata.mat');

python says that : 

Traceback (most recent call last):
  File "C:\Users\Ali\.spyder2-py3\template.py", line 14, in <module>
    mat = scipy.io.loadmat('rfdata.mat');
NameError: name 'scipy' is not defined

EDIT: I removed all code above and wrote 

import scipy.io as sio
mat = sio.io.loadmat('rfdata.mat');

still does not work

I appreciate your help

Thanks

As you did:

import scipy.io as sio

You loaded scipy.io into sio. So, when you call:

mat = scipy.io.loadmat('rfdata.mat');

scipy is not defined, but sio is:

mat = sio.loadmat('rfdata.mat')

Moreover:

  • try to place all imports at the begining of the file;
  • do not use ; at the end of a line, it is not needed in Python.
