Python Tuple

Tuples are immutable,meaning they cannot be changed once they are created.A tuple is a collection which is ordered and unchangeable.

Create a Tuple

We create a tuple by placing elements inside (),separated by commas.

ages =  (19, 26, 23)
print(ages) 

Output
(19, 26, 23)
              

Access Tuple Elements

We can access tuple items by referring to the index number,inside square bracket.

fruit = ("apple","banana","cherry")
 print(fruit[1])

Output
banana
              

Change Tuple Value

Once a tuple is created,we cannot change its values.Tuples are unchangable.

fruit=("apple","banana","cherry")
    for x in fruit:
        print(x)

Output
apple
banana
cherry
              

Tuple Length

To determine how many items a tuple has, use the len() function.

 fruit = ("apple", "banana", "cherry")
  print(len(fruit))

Output
3
              

Remove Items in Tuple

Since tuples are unchangable,so we cannot remove items from it but we can delete the tuple completely.

thistuple = ("apple", "banana", "cherry")
  del thistuple
  print(thistuple)

Output
File "/home/main.py",line 10, in <module>
print(thistuple)
NameError: name 'thistuple' is not defined
              

The above output shows that "thistuple" gets deleted completely.

Tuple Constructor

It is possible to use the tuple() constructor to make a tuple.

 thistuple  = tuple(("apple", "banana", "cherry"))
  print(thistuple)

Output
('apple', 'banana', 'cherry')
