Which is better?

while len(lst) > 0:

A dozen posts, but nobody has posted the right
answer yet, so I will :-)

It doesn't matter -- use whichever you prefer (*)
This is an angels on the head of a pin issue.

(*) -- If your code is part of an existing body of
code that uses one or the other style consistently,
then you should do the same.


I'd go even one step further. Turn it into English (or your favorite
non-computer language):

1. While list, pop.

2. While the length of the list is greater than 0, pop.

Which one makes more sense? Guess which one I like. CPU cycles be damned.

It looks like there are two crowds, terse and verbose. I thought terse
is perl style and verbose is python style. BTW, lst = [] was not what
I was interested in :-) I was asking whether it was better style to
use len() or not.
