Python Tuple Explained with Examples

Python tuple is an immutable data structure that stores a collection of elements.

Tuple Features

immutable – you cannot add, remove, or modify elements in a tuple after it’s created.
Ordered – It maintains the order of elements.
Homogeneous or Heterogeneous – Tuples can contain elements of the same type (homogeneous) or different types (heterogeneous).

You can create a tuple by enclosing a sequence of values in parentheses ()

my_tuple = (1, 2, 3, 4, 5)

You can also create an empty tuple by simply using parentheses without any values.

empty_tuple = ()

To create a tuple with a single element, a comma must follow the element.

single_element_tuple = (1,)

Similar to List, you also can use if statement to check if a tuple is empty or not.

if empty_tuple:
    print()
else:
print()

You can use len() method to get the length of the tuple (number of elements).

my_tuple = (1, 2, 3)
print(len(my_tuple))  # Output: 3

As to empty tuple, the length is 0.

Elements in a tuple are accessed using index values starting from 0

print(my_tuple[0])  # Output: 1

You can also use slicing to extract a subset of elements from a tuple.

tuple[start:stop:step]

start: The index where the slicing starts (inclusive).

stop: The index where the slicing stops (exclusive).

step (optional): The step value used to determine the increment between elements. Default is 1.

It returns a subset of a tuple.

Example:

my_tuple = (1, 2, 3, 4, 5)
print(my_tuple[1:3])  # Output: (2, 3)
print(my_tuple[:3])  # Output: (1, 2, 3)
print(my_tuple[2:])  # Output: (3, 4, 5)

Tuples can be iterated using for in loops.

for item in my_tuple: print(item)
    print(item)
