Tuple in Python (with Example)

  • Updated

Tuple in Python

A tuple is similar to a list but there is one difference between a tuple and a list, tuples are immutable means unchangeable. We cannot change its values.

Code

tuple_a = ("red", "yellow", "orange")

print(tuple_a)
Python
Output: (‘red’, ‘yellow’, ‘orange’)

Access Item

Access the first item from the tuple.

Code

tuple_a = ("red", "yellow", "orange")

print(tuple_a[1])
Python
Output: yellow

Change Specified Item from List

You can also change a third item from a list using its index.

Code

tuple_a = ["red", "yellow", "orange"]
tuple_a[2] = "black"  # Modify the third element (index 2) to "black"
print(tuple_a)
Python
Output: [‘red’, ‘yellow’, ‘black’]

Print a tuple using for loop

We can also use for loop to print tuple items in one go except printing one by one.

Code

tuple_a = ("red", "yellow", "orange")

for x in tuple_a:
    print(x)
Python
Output:
red
yellow
orange

Check if the Item exists or not:

Keywords give us the facility to check whether a specified key is present in a dictionary or not:

Code

tuple_a = ("red", "yellow", "orange")

if "red" in tuple_a:
    print("Yes 'red' is in the list")
Python
Output:  Yes ‘red’ is in the list

Add a new item in Tuple

You cannot add a new item to a tuple because as discussed above, tuples are unchangeable.

Code

tuple_a = ("red", "yellow", "orange")

# This will generate an error because tuples are immutable
# tuple_a[3] = "black"

print(tuple_a)
Python
Output:
(‘red’, ‘yellow’, ‘orange’)

Length of Tuple

Code

Print the number of total Items in the tuple using the len () method:

tuple_a = ("red", "yellow", "orange")

print(len(tuple_a))
Python
Output: 3

Remove item from Tuple

You cannot delete an item from a tuple because as discussed above, tuples are unchangeable.

Code

tuple_a = ("red", "yellow", "orange")

del tuple_a

# This will generate an error because tuple_a is no longer defined
# print(tuple
Python
Output:
NameError: name ‘tuple_a’ is not defined

Join Two Tuples

We can also join two tuples:

Code

tuple1 = ('one', 'two', 'three')
tuple2 = (1, 2, 3)

tuple3 = tuple1 + tuple2

print(tuple3)
Python
Output:
(‘one’, ‘two’, ‘three’, 1, 2, 3)

Create a Tuple by using the constructor

We can also create a tuple by using the built-in constructor tuple ():

Code

tuple_b = tuple(("red", "yellow", "orange"))

print(tuple_b)
Python

Note: Note the double-round brackets.

Output:
(‘red’, ‘yellow’, ‘orange’)

Tuple Unpacking

If tuples are in a list then we can unpack tuples using for loop.

Code

my_list = [(1,2), (3,4), (5,6), (7,8)]

for var in my_list:
    print(var)
Python
Output:
(1, 2)
(3, 4)
(5, 6)
(7, 8)

Access First Elements

Assess individual elements of Tuple from the List

Code

my_list = [(1,2), (3,4), (5,6), (7,8)]

for a in my_list:
    print(a)
Python
Output:
(1, 2)
(3, 4)
(5, 6)
(7, 8)

Accessing Second Element

Code

my_list = [(1,2), (3,4), (5,6), (7,8)]

for b in my_list:
    print(b)
Python
Output:
(1, 2)
(3, 4)
(5, 6)
(7, 8)
