How to check if a list is empty in Python?

Question

The API I'm working with can return empty [] lists.

What isn't working:

if myList is not None: #not working
if myList is not []: #not working

What will work?

Answer 1

if not myList:
  print "Nothing here"

Answer 2

Empty lists evaluate to False in boolean contexts (such as if some_list:).

Answer 3

I like Zarembisty's answer. Although, if you want to be more explicit, you can always do:

if len(my_list) == 0:
    print "my_list is empty"
