Python Set discard() method

The built-in method, discard() in Python, removes the element from the set only if the element is present in the set. If the element is absent in the set, then no error or exception is raised and the original set is printed.

Python Set discard(): The element is present

In this example, the element that we wanted to remove is present inside the set and we remove that element with the help of the discard() method.

Output:

{41, 10, 26, 54}

Python discard() in the Absence of the Element

In this example, the element that we wanted to remove is not present inside the set and when we try to remove that element from the set then nothing is removed and no exception is thrown.

Output:

{41, 10, 26, 20, 54}

In this article, we will see how to remove an element in a set, using the discard() and remove() method. We will also learn the difference between the two methods, although they produce the same results.

Example

Input: set = ([10, 20, 26, 41, 54, 20])
Output: {41, 10, 26, 54}
Input: set = (["ram", "aakash", "kaushik", "anand", "prashant"])
Output: {'ram', 'prashant', 'kaushik', 'anand'}
