N-Gram in Python

I used python-ngram

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import ngram

text = u'AIUEO'
index = ngram.NGram(N=2)
for term in index.ngrams(index.pad(text)):
    print term

result

$ python sample.py 
$Ah
Ai
Say
up
Eo
O$

There are many other functions, so you should read the tutorials linked above. It seems that you can also search

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import ngram

G = ngram.NGram(['joe','joseph','jon','john','sally'])
print G.search("joseph")

$ python sample.py
[('joseph', 1.0), ('joe', 0.18181818181818182), ('jon', 0.18181818181818182), ('john', 0.16666666666666666)]
