Are you certain that this is what you typed?

C:\Users\Mark\Desktop>py -2.7
Python 2.7.10 (default, May 23 2015, 09:44:00) [MSC v.1500 64 bit 
(AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> import matplotlib.pyplot as plt
 >>>

Please have another go.

The above is incorrect, you are trying to import 'pyplot' from 
'matplotlib.pyplot'.

With this type of problem I'm inclined to throw the last line of the 
traceback, here the 'AttributeError' one, into a search engine and see 
what you come up with.  The hits you get are often enough to help you 
diagnose the problem.
