The program below creates a stream with the numbers 1..995 and then filters the stream, keeping only the even numbers, and then prints the second number in the stream (implemented as the first number of the tail, just like in the 3.5 Section in the Wizard book).
How's this:
Py> from itertools import islice Py> print islice((x for x in xrange(1, 996) if x % 2 == 0), 1, 2).next() 4
Wouldn't it be nice if this could be spelt:
print (x for x in xrange(1, 996) if x % 2 == 0)[2]
Well, I just put a patch on SF to enable exactly that: http://www.python.org/sf/1108272
Cheers, Nick.
