Python Sets and Set Operations

Sets are unordered collections in Python that do not allow duplicate elements. Let's explore sets and common set operations:

1. Creating Sets

Sets are created using curly braces `{}` or the `set()` constructor.

# Example
my_set = {1, 2, 3, 4, 5}
        

2. Common Set Operations

Python supports various set operations, including union, intersection, and difference.

# Example
set1 = {1, 2, 3, 4, 5}
set2 = {3, 4, 5, 6, 7}

union_set = set1 | set2  # Union
intersection_set = set1 & set2  # Intersection
difference_set = set1 - set2  # Difference
        

3. Modifying Sets

Sets are mutable, allowing the addition and removal of elements.

# Example
my_set.add(6)  # Adding an element
my_set.remove(3)  # Removing an element
