Python has a set of built-in methods that you can use on sets. Learn more about sets in our Python Sets Tutorial. Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java, XML and more.
Remove an element from this set if it is a member, otherwise do nothing. >> s = {'Alice', 'Bob', 'Cloe'} >>> s.discard('Bob') # s == {'Alice', 'Cloe'} set.intersection() Return a new set of elements that are members of this and the set argument(s). >> {1, 2, 3, 4}.intersection({3, 4, 5}) {3, 4}
Data Structure - Sets. Another data type in Python is sets. It is a type that could store an unordered collection with no duplicate elements. It is also support the mathematical operations like union, intersection, difference, and symmetric difference.
4 wrz 2023 · In this guide to Python sets, we will start by defining what they are. Then we’ll teach you all about set operations in Python and explore the methods available for Python sets. Finally, we’ll explain how we can leverage sets in some relevant use cases. This article assumes that you have basic Python knowledge. If that’s not the case, don’t worry!
Sets. Sets are an unordered collection of unique elements. >> basket = [’apple’, ’orange’, ’apple’, ’pear’, ’orange’, ’banana’] >> fruit = set(basket) # create a set. >> fruit. set([’orange’, ’pear’, ’apple’, ’banana’]) > ’orange’ in fruit # fast membership testing. True.
In this tutorial, we will learn Set and its various operations in Python with the help of examples.
