In Python, sets are a collection data type that is unordered and unindexed. They can be used to perform various operations such as union, intersection, and difference. To search or check for membership in a set, you can use the `in` keyword, which allows you to easily determine if an element exists within the set.
Here’s an example demonstrating how to search for elements within a set:
# Define a set
my_set = {1, 2, 3, 4, 5}
# Search for an element
if 3 in my_set:
print("3 is in the set.")
else:
print("3 is not in the set.")
# Searching for an element that is not in the set
if 6 in my_set:
print("6 is in the set.")
else:
print("6 is not in the set.")
