2.6 Tuple:

In list we can add, delete or modify any element but in tuple we can nod add any add, delete or modify any element from tuple.

A tuple is a collection which is ordered and unchangeable.

In Python tuples are written with round brackets.

tuple = ("Apple", 10.4, 10)
print(tuple)

Output:    
    (‘Apple’, 10.4, 10)

2.6.1 Accessing Tuple Elements:

   

tuple = ("Apple", 10.4, 10)
print(tuple[1])

Output:    
    10.4

Note: Once we create a tuple, then we can not change, modify or delete any element from tuple but we can delete complete tuple. Only we can access tuple.

tuple = ("Apple", 10.4, 10)
for x in tuple:
    print(x)

Output:    
Apple    
10.4    
10

2.6.2 Check if Item Exists:

    Check if "apple" is present in the tuple:

       

tuple = ("Apple", 10.4, 10)
if "Apple" in tuple:              
    print("Yes, 'Apple' is in the fruits tuple")    

Output:        
    Yes, 'Apple' is in the fruits tuple

2.6.3 Tuple Length:

    To determine how many items a tuple has, use the len() method:

       

tuple = ("Apple", 10.4, 10)
print(len(tuple))

Output:    
    3
