I would also add that, if the primary goal of your class is to
encapsulate the data, you can do
class MyClass:
def __init__(self, ...):
self.data = []
def __len__(self):
return len(self.data)
which allows for the even clearer
my_obj = MyClass(...)
manipulate(my_obj)
if len(my_obj) > 42:
do_important_stuff()
-tkc
