Python Tuple

Tuple is an ordered collection of data or elements which are immutable and placed within the round brackets.

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
print(fruits)
  

Output

Access Tuple Items

To access the items or elements of a tuple, you can simply refer to the item index number.

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
print(fruits[2])
  

Output

Access Tuple Items Using Negative Index

The negative index starts from the last item of a tuple in Python.

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
print("Item at index -1 is " + fruits[-1])
print("Item at index -2 is " +fruits[-2])
print("Item at index -3 is " +fruits[-3])
  

Output

Access Tuple Items Using Range Index

Items of a tuple can also be accessed by specifying range of indexes, the start index and the end index separated by colon.

Syntax

tuple[start index : end index]

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
print(fruits[1:3])
  

Output

A tuple items can also be accessed using negative index with range. Negative index starts the search from the last index of a tuple.

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
print(fruits[-3:-1])
  

Output

Loop Through Tuple

Items of a tuple can also be accessed by using the for loop.

Syntax

tuple[start index : end index]

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
for i in fruits:
    print(i)
  

Output

Check if Item Exists in Tuple

To check for existence of items in a tuple, you can use the in keyword.

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
if "apple" in fruits:
    print("apple exists")
  

Output

Tuple Length

To get the length of a tuple, you can use the len() function.

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
print(len(fruits))
  

Output

Tuple Add Items

Tuple is immutable which means after the tuple is created, new items in tuple cannot be added and existing items cannot be deleted. The example below will show error.

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
fruits[2] = "banana"
  

Create Tuple using tuple() constructor

A tuple can also be created using the tuple() constructor.

Example

colors = tuple(("white", "green", "yellow", "blue", "red"))
print(colors)
  

Output

Join Two Tuples

In Python, two tuples can be added together using the + operator.

Example

fruits = ("mango", "grapes", "guava", "apple", "watermelon")
colors = ("white", "green", "yellow", "blue", "red")
tuples = fruits + colors
print(tuples)
  

Output
