How to Access Tuple Elements in Python: A Simple Guide

We can access the objects of a tuple in a variety of ways.

Indexing

To access an object of a tuple, we can use the index operator [], where indexing in the tuple starts from 0.

A tuple with 5 items will have indices ranging from 0 to 4. An IndexError will be raised if we try to access an index from the tuple that is outside the range of the tuple index. In this case, an index above 4 will be out of range.

We cannot give an index of a floating data type or other kinds because the index in Python must be an integer. TypeError will appear as a result if we give a floating index.

The example below illustrates how indexing is performed in nested tuples to access elements.

Example

# Python program to show how to access tuple elements  
  
# Creating a tuple  
tuple_ = ("Python", "Tuple", "Ordered", "Collection")  
  
print(tuple_[0])    
print(tuple_[1])   
# trying to access element index more than the length of a tuple  
try:  
    print(tuple_[5])   
except Exception as e:  
    print(e)  
# trying to access elements through the index of floating data type  
try:  
    print(tuple_[1.0])   
except Exception as e:  
    print(e)  
  
# Creating a nested tuple  
nested_tuple = ("Tuple", [4, 6, 2, 6], (6, 2, 6, 7))  
  
# Accessing the index of a nested tuple  
print(nested_tuple[0][3])         
print(nested_tuple[1][1])     

Output

Python
Tuple
tuple index out of range
tuple indices must be integers or slices, not float
l
6

Negative Indexing

Python's sequence objects support negative indexing.

The last item of the collection is represented by -1, the second last item by -2, and so on.

Example

# Python program to show how negative indexing works in Python tuples  
  
# Creating a tuple  
tuple_ = ("Python", "Tuple", "Ordered", "Collection")  
  
# Printing elements using negative indices  
print("Element at -1 index: ", tuple_[-1])  
  
print("Elements between -4 and -1 are: ", tuple_[-4:-1])  

Output

Element at -1 index:  Collection
Elements between -4 and -1 are:  ('Python', 'Tuple', 'Ordered')

Slicing

We can use a slicing operator, a colon (:), to access a range of tuple elements.

Example

# Python program to show how slicing works in Python tuples  
  
# Creating a tuple  
tuple_ = ("Python", "Tuple", "Ordered", "Immutable", "Collection", "Objects")  
  
# Using slicing to access elements of the tuple  
print("Elements between indices 1 and 3: ", tuple_[1:3])  
  
# Using negative indexing in slicing  
print("Elements between indices 0 and -4: ", tuple_[:-4])  
  
# Printing the entire tuple by using the default start and end values.   
print("Entire tuple: ", tuple_[:])  

Output

Elements between indices 1 and 3:  ('Tuple', 'Ordered')
Elements between indices 0 and -4:  ('Python', 'Tuple')
Entire tuple:  ('Python', 'Tuple', 'Ordered', 'Immutable', 'Collection', 'Objects')
