Tuples in Python

• A tuple is an immutable list means non-changeable list.
• Tuples are ordered in nature.
• Values can be accessed by index.
• Various operations can be performed like Iteration, looping , concatenation.
• Used when data is fixed and not require any changes.

Syntax

tuple_name = (item1,item2...itemN)

tuple_name =(item1 ,)          # for single item comma is required at end

Accessing values of tuples

persons = ('Akshat','Raju','Bhanu','Naresh','Pareek')
for i in persons:
    print(i)

OUTPUT : 
Akshat                                                                                                                                                   
Raju                                                                                                                                                     
Bhanu                                                                                                                                                    
Naresh

You cannot modify the tuples as they are immutable

persons = ('Akshat','Raju','Bhanu','Naresh','Pareek')
persons[0]='Akshita'
print(persons[0])

OUTPUT : TypeError: 'tuple' object does not support item assignment 

persons = ('Akshat','Raju','Bhanu','Naresh','Pareek')

try :
    del persons[0]
except :
    print("Tuples items cannot be deleted")

OUTPUT : Tuples items cant be deleted 

Assigning tuples values to multiple variables at once

persons = ('Akshat','Raju')
(first, second) = persons
print(first)
print(second)

OUTPUT : 
Akshat                                                                                                                                                   
Raju

Deleting a tuple

persons = ('Akshat','Raju')
del persons

To convert tuple into list

persons = ('Akshat','Raju','Goli')
persons_list=list(persons)
print(persons_list)

OUTPUT : ['Akshat', 'Raju', 'Goli']
