Function Details: len

Description

Returns the length (the number of items) of an object.

Extended Description

The len() function returns the number of items in an object. The argument may be a sequence (such as a string, bytes, tuple, list, or range) or a collection (such as a dictionary, set, or frozen set). For mappings, len() returns the number of keys. For custom objects, len() calls the object's __len__() method.
