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
I like it. Of course you always have to bear in mind that one giant leap for
a list could be _many_ small steps for an iterator.
Indeed. The main cases I am thinking of involve picking off the first few items of an iterator (either to use them, or to throw them away before using the rest).
And if an app actually *needs* random access, there's a reason lists still exist ;)
Cheers, Nick.
