Reading .eml files with Python 3.6 using emaildata 0.3.4

I am using python 3.6.1 and I want to read in email files (.eml) for processing. I am using the emaildata 0.3.4 package, however whenever I try to import the Text class as in the documentation, I get the module errors:

import email
from email.text import Text
>>> ModuleNotFoundError: No module named 'cStringIO'

When I tried to correct using this update, I get the next error relating to mimetools

>>> ModuleNotFoundError: No module named 'mimetools'

Is it possible to use emaildata 0.3.4 with python 3.6 to parse .eml files? Or are there any other packages I can use to parse .eml files? Thanks
