Tuple

Python tuple is a sequence, which can store heterogeneous data types such as integers, floats, strings, lists, and dictionaries. Like strings, tuple is immutable.

Creating an empty tuple

<variable –name > = ()
Tup1 = ()

The empty tuple is written as two parentheses containing nothing.

Creating tuple with elements

To create a tuple, fill the values in tuple separated by commas:

tup1 = (1,2,3,4.6, "hello", "a")

If you define the variable as follows:

a = 1,2,3

The variable a would be a tuple:

>>> tup1 = 1,2,3,4
>>> tup1
(1, 2, 3, 4)
>>> 
>>> type(tup1)
<type 'tuple'>
>>>

 

 

Indexing tuple

In order to access a particular value of tuple, specify a position number, in brackets. Let's discuss with an example. I am going to make a tuple of the heroes from the movie Avengers.

>>> Avengers = ("iron-man", "vision", "Thor", "hulk")
>>> Avengers[0]
'iron-man'
>>> Avengers[2]
'Thor'
>>> 
>>> Avengers[-1]
'hulk...
