Python Tuple

Python tuple is a list of immutable objects with heterogeneous data. Tuples are enclosed in brackets () with items comma separated.

How to create a tuple in Python?

Tuple in Python is created using small brackets () with the items in the tuple be separated by a comma (,).  A tuple can have any number of items and can be of different data types. To have an idea of python data types, please refer to this tutorial:- Python Datatypes.

Let’s explore some of the examples of the tuple in the following example:-

tuple = ( 'abcd', 786 , 2.23, 'john', 70.2  )
list = [ 'abcd', 786 , 2.23, 'john', 70.2  ]
tuple[2] = 1000    # Invalid syntax with tuple
list[2] = 1000     # Valid syntax with list

• An empty tuple can be written as tuple = ()
• The tuple having a single value must include a comma as tuple = (2,)
• No Enclosing Delimiters can be used for creating a tuple
  tuple = ‘a’, 123, 2.4, ‘John’

How to access elements in a tuple in Python?

We can use a slice operator [] and [:] to get items in the tuple. The concatenation operation can be done using plus (+) sign and asterisk(*) serves as the repetition operator. We can use two types of indexing to get items viz. positive indexing and negative indexing. Positive indexing allows to index items from 0 to n where negative index gives access from backward, where -1 is the last item.

Below is an example of tuple with simple operations:-

tuple = ('abcd', 786 , 2.23, 'john', 70.2)
print(tuple)          #Prints complete tuple
print(tuple[0])       #Prints first element of the tuple
print(tuple[1:3])     #Prints elements starting from 2nd till 3rd
print(tuple[2:])      #Prints elements starting from 3rd element
print(tuple[-1])      #Prints last element

Output:-

How to change or add elements to a tuple in Python?

Since tuples are immutable data types, you cannot add, edit or delete any item in a tuple.

colors = ('red', 'green', 'blue')
print("Current tuple", colors)
colors = ('black', 'gray', 'blue')
print("Updated new color", colors)

colors[1] = 'black'

 How to delete or remove elements from a Tuple in Python?

As tuples are immutable, we cannot delete individual items in tuple, but the tuple can be deleted as a whole using del function.

How to iterate over a Tuple in Python?

A tuple can be iterated using for loop. Let us see the following example:-

colors = ('red', 'green', 'blue', 'gray', 'black')
for color in colors:
    print(color)
