A real-time example of using tuples in Python could be representing coordinates in a 2D plane. Let’s say you’re working on a mapping application and you need to store the coordinates of various locations.
Tuples can be useful in this scenario because they provide an immutable and ordered collection of values.
Here’s an example:
# Storing coordinates using tuples
location1 = (37.7749, -122.4194) # San Francisco
location2 = (51.5074, -0.1278) # London
location3 = (-33.8651, 151.2099) # Sydney
# Accessing tuple elements
print(f"Latitude: {location1[0]}, Longitude: {location1[1]}")
print(f"Latitude: {location2[0]}, Longitude: {location2[1]}")
print(f"Latitude: {location3[0]}, Longitude: {location3[1]}")Code language: Python (python)In this example, each tuple represents the latitude and longitude coordinates of a specific location.
The values inside the tuple are immutable, meaning they cannot be modified once defined.
You can access individual elements using indexing, such as location1[0] for latitude and location1[1] for longitude.
Tuples are particularly useful when you want to group related values together but don’t need to modify them later.
They can be used in various other scenarios as well, depending on your specific programming needs.

Where are tuples used in Python in real life?
Here’s another real-time example of using tuples in Python: representing a student’s information.
# Storing student information using tuples
student1 = ("John Doe", 20, "Computer Science")
student2 = ("Jane Smith", 19, "Mathematics")
student3 = ("David Johnson", 21, "Physics")
# Accessing tuple elements
print(f"Name: {student1[0]}, Age: {student1[1]}, Major: {student1[2]}")
print(f"Name: {student2[0]}, Age: {student2[1]}, Major: {student2[2]}")
print(f"Name: {student3[0]}, Age: {student3[1]}, Major: {student3[2]}")
In this example, each tuple represents a student’s information, including their name, age, and major. The elements within the tuple are ordered, and you can access them using indexing.
For instance, student1[0] gives the student’s name, student1[1] gives their age, and student1[2] gives their major.
Tuples are suitable in this context because they allow you to group related pieces of information together as a single entity.
Since student information is not expected to change frequently, tuples provide an immutable data structure for representing this data.
