Summary: in this tutorial, you’ll learn how to use the Python issuperset() method to check if a set is a superset of another. Introduction to Python issuperset method Suppose that you have two sets: A and B. Set A is a superset of set B if all elements of set B are elements of set A. If set A…

Summary: in this tutorial, you’ll learn how to use the Python issuperset() method to check if a set is a superset of another. Introduction to Python issuperset method Suppose that you have two sets: A and B. Set A is a superset of set B if all elements of set B are elements of set A. If set A…

Summary: in this tutorial, you’ll learn about how to use the Python issubset() method to check if a set is a subset of another set. Introduction to the Python issubset() method Suppose that you have two sets A and B. Set A is a subset of set B if all elements of A are also elements of B. Then,…

Summary: in this tutorial, you’ll learn how to find the symmetric difference between two or more sets in Python. Introduction to the symmetric difference of sets The symmetric difference between two sets is a set of elements that are in either set, but not in their intersection. Suppose that you have the following s1 and s2 sets: The symmetric…

Summary: in this tutorial, you’ll learn about the Python Set difference and how to use it to find the difference between two or more sets. Introduction to the Python Set difference The difference between the two sets results in a new set that has elements from the first set which aren’t present in the second set. Suppose…

Summary: in this tutorial, you’ll learn about the Python set intersection and how to use it to intersect two or more sets. TL;DR In Python, you can use the set intersection() method or set intersection operator (&) to intersect two or more sets: The intersection() method and & operator have the same performance. Introduction to Python set intersection…

Summary: in this tutorial, you’ll learn how to union two or more sets by using the Python set union() or set union operator (|). Introduction to the set union The union of two sets returns a new set that contains distinct elements from both sets. Suppose that you have the following sets: The union of the s1 and s2…

Summary: in this tutorial, you’ll learn how to use Python set comprehension to create a new set based on an existing one. Introduction to Python Set comprehension Suppose that you have the following set that consists of three tags: To convert the tags in the set to another set of tags in lowercase, you may use the…

Summary: in this tutorial, you’ll learn about Python Set type and how to use it effectively. Introduction to the Python Set type A Python set is an unordered list of immutable elements. It means: To define a set in Python, you use the curly brace {}. For example: Note a dictionary also uses curly braces, but its elements…
