Immutable Data Type, Tuple
A tuple is a data type in Python used to store multiple values in a specific order, similar to a list. However, unlike lists, tuples are immutable, meaning their contents cannot be changed after creation.
This immutability makes tuples ideal for storing fixed data, 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 without parentheses by simply separating the values 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])
