How do I merge sets in Python in pure Python?

In Python, you can merge sets using the union operator `|` or the `union()` method. Both methods allow you to combine two or more sets into a single set that contains all unique elements from the original sets.

Here's how you can do it:


        # Example of merging sets in Python
        set1 = {1, 2, 3}
        set2 = {3, 4, 5}
        
        # Using the union operator
        merged_set = set1 | set2
        print(merged_set)  # Output: {1, 2, 3, 4, 5}

        # Using the union() method
        merged_set_method = set1.union(set2)
        print(merged_set_method)  # Output: {1, 2, 3, 4, 5}
