better in what sense?
timeit -s "from test import sampledict" "keys = [key for key in sampledict if
sampledict[key] ==
1974]"
100000 loops, best of 3: 2.27 usec per loop
timeit -s "from test import sampledict" "keys = [key for key,year in
sampledict.iteritems() if year
== 1974]"
100000 loops, best of 3: 2.56 usec per loop
