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. A set is useful because it contains unique elements. Below is a list of the set operations available in Python. Sets are used to store multiple items in a single variable. You might have noticed that methods like insert, remove or sort that only modify the list have no return value printed – they return the default None. Python - Sets - Mathematically a set is a collection of items not in any particular order. You can use a set to get the unique elements. There are a few ways to get a list of unique values in Python. # Define a list heterogenousElements = [3, True, 'Michael', 2.0] The list contains an int, a bool, a string, and a float. 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. You may learn more: Sets and its Methods in Python Python is simple, but not simpler as to do: c.upper() Both the list have common elements 3 & 5, So it will return [3,5].
