The bool() function in Python is a built-in function that returns the boolean value of a specified object. It evaluates the truth value of an object, returning True if the object is true and False if the object is false. Objects that are considered false include empty objects like empty strings, lists, tuples, and dictionaries, as well as numerical values of zero. Other objects are considered true.
