i will go against the grain slightly and say that "len" is probably the best compromise in most situations (although i admit i don't know what count is) because i think it will work when you expect it to and break when you have a bug in your program.
using a simple boolean is more robust (and what i typically do in my own code because i am often too lazy to think carefully), but if it is given something that is not "list-like" you won't get an error until later in your code (and typically the sooner an error is found, the better). but i may be wrong - are there any containers (apart from pathological hand-crafted examples) that would not define __len__()? andrew srinivasan srinivas wrote: > > For ex: to check list 'A' is empty or not.. > if A == []: > if A.count == 0: > if len(A) == 0: > if not A: > > Thanks, > Srini > > > Add more friends to your messenger and enjoy!
