Python Coding challenge - Day 166 | What is the output of the following Python Code?

 

Code:

set1 = {1, 2, 3}

set2 = {3, 4, 5}

print(set1 - set2)

Solution and Explanation:

The code snippet set1 = {1, 2, 3} and set2 = {3, 4, 5} initializes two sets: set1 containing elements {1, 2, 3} and set2 containing elements {3, 4, 5}.

When you perform the operation set1 - set2, you're using the set difference operator -, which returns a new set containing elements that are present in set1 but not in set2. In other words, it returns the elements that are unique to set1.

So, in this case, the output will be {1, 2} because the elements 1 and 2 are present in set1 but not in set2. The element 3 is common to both sets, so it is not included in the result.
