I was looking at some word count code and thought a more functional approach would be better and more fun to code.

Python, 1 line
1
lengths = map(lambda word: len(word), open("foo.txt","r").readline().split())

This method was used for its simplicity.

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"))))
