It shouldn't be about saving code. There's no shortage of code so that we 
have to conserve it. But there is a shortage of time and effort, so 
making your code easy to read and easy to maintain is far more important.

for x in (2**i for i in xrange(10)):
    print x

will also print 1, 2, 4, 8, ... up to 1000.
