In Python, a set is a collection that is unordered, mutable, and does not allow duplicate elements. Sets are useful when you need to store unique items and perform operations such as union, intersection, and difference. You can create a set by using curly braces or the `set()` function.
Here are two common ways to create a set in Python:
my_set = {1, 2, 3, 4, 5}
my_set = set([1, 2, 3, 4, 5])
# Creating a set
my_set = {1, 2, 3, 4, 5}
# Adding an element
my_set.add(6)
# Removing an element
my_set.remove(3)
# Displaying the set
print(my_set) # Output: {1, 2, 4, 5, 6}
