The Python list() constructor returns a list in Python. A Python set is similar to this mathematical definition with below additional condit In this tutorial, we will learn to use list() in detail with the help of examples. set() method is used to convert any of the iterable to sequence of iterable elements with distinct elements, commonly called Set. If both lists do not contain any common elements then it will return an empty list. # Define a list heterogenousElements = [3, True, 'Michael', 2.0] The list contains an int, a bool, a string, and a float.

Both the list have common elements 3 & 5, So it will return [3,5]. The principle outlined above generally applies: where a set is expected, methods will typically accept any iterable as an argument, but operators require actual sets as operands. Some are performed by operator, some by method, and some by both. Python lists are very similar to an array but the main difference is, an array can store only one type of element whereas, a list can store different types of elements. Then, turn the set into a list. Set, a term in mathematics for a sequence consisting of distinct language is also extended in its language by Python and can easily be made using set().
