In this article, we will dive deep into the different set operations available in Python and illustrate how to use them in code examples. By the end of this article, you will have a comprehensive understanding of the different set operations in Python and how they can be applied to solve real-world problems.
Set Operations in Python
In Python, sets are a data structure that stores an unordered collection of unique elements. Sets are widely used in Python because they allow developers to perform an intersection, union, and symmetric differences. These operations can be performed using built-in functions.
Intersection
The intersection operation returns a set containing elements common to both sets. We can use the ‘&’ operator or the intersection() method to perform an intersection operation on two sets. For example:
set1 = {1, 2, 3}
set2 = {2, 3, 4}
intersection_set = set1 & set2
print(intersection_set) # Output: {2, 3}
Union
The union operation returns a set containing all elements from both sets without any duplicates. To perform a union operation on two sets, we can use the ‘|’ operator or the union() method. For example:
set1 = {1, 2, 3}
set2 = {2, 3, 4}
union_set = set1 | set2
print(union_set) # Output: {1, 2, 3, 4}
Difference
The difference operation returns a set containing elements in the first set but not in the second one. We can use the ‘-‘ operator or the difference() method to perform a difference operation on two sets. For example:
set1 = {1, 2, 3}
set2 = {2, 3, 4}
difference_set = set1 - set2
print(difference_set) # Output: {1}
Symmetric Difference
The symmetric difference operation returns a set containing elements that are either in the first or second set but not in both. We can use the ‘^’ operator or the symmetric_difference() method to perform a symmetric difference operation on two sets. For example:
set1 = {1, 2, 3}
set2 = {2, 3, 4}
symmetric_difference_set = set1 ^ set2
print(symmetric_difference_set) # Output: {1, 4}
We have explored the different set operations in Python and illustrated how to use them in code examples. Developers can manipulate sets and solve real-world problems by using these operations. Whether you are a beginner or an experienced Python developer, understanding set operations is crucial for mastering Python.
