Tuples, as opposed to lists, are immutable objects.

This implies that after a tuple's elements have been specified, we cannot modify them. However, we can modify the nested elements of an element if the element itself is a mutable data type like a list.

A tuple can be assigned to many values (reassignment).

Example

# Python program to show that Python tuples are immutable objects  
  
# Creating a tuple  
tuple_ = ("Python", "Tuple", "Ordered", "Immutable", [1,2,3,4])  
  
# Trying to change the element at index 2  
try:  
    tuple_[2] = "Items"  
    print(tuple_)  
except Exception as e:  
    print( e )  
  
# But inside a tuple, we can change elements of a mutable object  
tuple_[-1][2] = 10   
print(tuple_)  
  
# Changing the whole tuple  
tuple_ = ("Python", "Items")  
print(tuple_)   

Output

'tuple' object does not support item assignment
('Python', 'Tuple', 'Ordered', 'Immutable', [1, 2, 10, 4])
('Python', 'Items')

To merge multiple tuples, we can use the + operator. Concatenation is the term for this.

Using the * operator, we may also repeat a tuple's elements for a specified number of times. This is already shown above.

The results of the operations + and * are new tuples.

Example

# Python program to show how to concatenate tuples  
  
# Creating a tuple  
tuple_ = ("Python", "Tuple", "Ordered", "Immutable")  
  
# Adding a tuple to the tuple_  
print(tuple_ + (4, 5, 6))  

Output

('Python', 'Tuple', 'Ordered', 'Immutable', 4, 5, 6)
