Function to return number of words in a string?

Hiya-

I'm looking for a function to return the number of words in a string,
split on whitespace. I'm coming from python, so I may just write it in
that but I wanted to check first. In python, one would write:

s="some string or other"
len(s.split())

Thanks!
