Immutable Data Type, Tuple

A tuple is a data type that stores multiple values in order, similar to a list, but once created, its content cannot be changed due to its immutability.

This immutability makes tuples useful for safely storing values that must not be altered, such as coordinates of a specific location or color values.


How do you define a tuple?

A tuple is created by enclosing elements in parentheses () and separating each element with a comma ,.

Tuple Declaration Example
my_tuple = (1, 2, 3)

print(my_tuple) # (1, 2, 3)

You can also define a tuple by omitting the parentheses and simply separating the elements with commas.

Tuple Declaration without Parentheses Example
my_tuple = 1, 2, 3

print(my_tuple) # (1, 2, 3)

How do you use a tuple?

Tuples are used to safely store values in a program that should not change.

For example, in a map-related program, you can use a tuple to store the latitude and longitude of a specific location.

Tuple Example
# Latitude and longitude of New York
coordinates = (40.7128, 74.0060)

# Print the first element, 40.7128
print("Latitude of New York:", coordinates[0])

# Print the second element, 74.0060
print("Longitude of New York:", coordinates[1])
