Word count and length with map and lambda (Python recipe) by Michael Thamm

ActiveState Code (http://code.activestate.com/recipes/578474/)

An even better approach is to simply do this:

from itertools import chain
lengths = list(chain(*list(list(len(word) for word in line.split()) for line in open("foo.txt", "r"))))

Actually I'm stupid :) Just:

from itertools import chain
lengths = list(chain(*((len(word) for word in line.split()) for line in open("foo.txt", "r"))))
