In Python, sets are an unordered collection of unique elements. They are useful in production systems for operations such as membership testing and eliminating duplicate entries. Here's how you can create and manipulate sets in Python:
# Creating a set
my_set = {1, 2, 3, 4, 5}
# Adding an element
my_set.add(6)
# Removing an element
my_set.discard(4)
# Checking if an element exists in the set
if 3 in my_set:
print("3 is in the set")
# Creating a set from a list to remove duplicates
my_list = [1, 2, 2, 3, 4, 4, 5]
unique_set = set(my_list)
