This built-in method also removes elements from the set but differs from the remove method we discussed earlier. If the element is present in the set, it removes the element, but if it is present, it returns no error and normally prints the set. We will see an example of this. Code:...
In the following sections, you’ll learn about these methods and how to use them in your Python code. Adding an Element With .add() The .add() method allows you to add a single element to an existing set. Below is a quick example that shows how this method works: Python >>> ...
Whenever you use a remove() method, you try to remove an element that is not there in the set. 1 2 3 4 5 #!/usr/bin/python A = {1, 2, 4, 5, 7, 9, 10, 14, 15, 17, 18} A.remove(100) print(A) Output: KeyError: 100 I will try to remove 100, which is not there...
All the operations that could be performed in a mathematical set could be done with Python sets. We can perform set operations using the operator or the built-in methods defined in Python for the Set. The following table will summarize the set operations and the corresponding set method used....
There are several ways to join two or more sets in Python. Theunion()andupdate()methods joins all items from both sets. Theintersection()method keeps ONLY the duplicates. Thedifference()method keeps the items from the first set that are not in the other set(s). ...
1. What is the primary use of the join method in Python sets? A. To merge two sets B. To find the intersection of sets C. To remove duplicates D. To sort sets Show Answer 2. Which of the following methods can be used to join two sets in Python? A. set.add() B. ...
Check For Disjoint Sets Using The isdisjoint() Method Instead of the approach discussed above, we can use the isdisjoint() method to check for disjoint sets in python. The isdisjoint() method, when invoked on a set, takes another set as an input argument. After execution,it returns True if...

To add an element to a set, you can use the add() method: my_set = {1, 2, 3} my_set.add(4) print(my_set) # {1, 2, 3, 4} Try it Yourself » Copy To remove an element from a set, you can use the remove() or discard() method: my_set = {1, 2, 3, 4} my...
