Python Coding challenge - Day 99 | What is the output of the following Python Code?

The discard() method in Python is used to remove a specified element from a set. If the element is not present in the set, discard() does nothing and does not raise an error.

In the code 

s = {1, 3, 7, 6, 5}

s.discard(4)

print(s)

The element 4 is not present in the set s, so the discard() method will do nothing. The output will be the original set:

{1, 3, 5, 6, 7}

The set s remains unchanged because the attempt to discard the non-existent element 4 has no effect.
