and this name is the important thing.
for i in something:
is a loop. I have to look at what it iterates over, what the loop is doing,
etc to get my head around it. When i see reduce(operator.add, foo) I know
what is happening in one succinct bite.
This is important for OTHER people who read your code. In python the loops
are fairly standard but in say java or C++ replacing a loop with a named
function is a definite win.
