Len() returns the number of items (the length) of a list object (also works for dictionary, string, tuple or range objects). So a list object does not have a simple length attribute len but rather the magic __len__(). For a normal list both are equivalent, but length_hint makes it possible to get the length of a list. It works by calling an object's __len__ method. Len is a function to get the length of a collection. 28 besides len you can also use operator.length_hint (requires python 3.4+).

Len is a function to get the length of a collection. 28 besides len you can also use operator.length_hint (requires python 3.4+). I found two ways to determine how many elements are in a variable… i always get the same values for len () and size (). Could size () have come with an.
