Question 
How to check if a word is an English word with Python? I believe nltk wordnet interface might be the way to go but I have no clue how to use it for such a simple task. 

How-To 
For (much) more power and flexibility, use a dedicated spellchecking library like PyEnchant. There's a tutorial, or you could just dive straight in: 

>>> import enchant 
>>> d = enchant.Dict("en_US") 
>>> d.check("Hello") 
True 
>>> d.check("Helo") 
False 
>>> d.suggest("Helo") 
['He lo', 'He-lo', 'Hello', 'Helot', 'Help', 'Halo', 'Hell', 'Held', 'Helm', 'Hero', "He'll"]
