Predictive text program?

Question

I want to write something that takes a sample text file, reads it, learns, and implements the vocabulary and sentence structure to make predicted sentences in the same style as the input text. I am not as skilled with machine learning as I should be, though. How could I do this?
edit* What program would be the most efficient at accomplishing this? I am most proficient in Python (ignore my in-app rating. I am lazy and haven't finished the modules)

Answer 1

Check out the Natural Language Toolkit, it has a rich support in Python and is really powerful:
