Python Tutorial

A tuple is an arrangement of immutable, ordered items. Since both tuples and Python lists are sequences, they are analogous. Tuples and lists, however, vary since we cannot edit tuples; however, we can change lists after initializing them. Additionally, we build tuples using parentheses, whereas we make lists using square brackets.

A tuple is created by putting different values inside the parenthesis, separated by commas. For example,

Example of a Tuple

tuple_1 = ("Tuples", "Lists", "immutable", "Mutable")  
tuple_2 = (3, 5, 7, 2, 6, 7)  
tuple_3 = "Tuples", "Lists", "immutable", "Mutable"  

You can create an empty tuple object by giving no elements in parentheses in an assignment statement. The built-in function of Python, tuple(), also creates a blank tuple object when it is called without any arguments.

Code

# Python program to show how to create an empty tuple

T1 = ()
print(T1)

T2 = tuple()
print(T2)

Output:

()
()

How to Check Empty Tuple in Python?

You can generate an empty tuple by placing no components in parenthesis in the assignment phrase. The built-in method tuple() also creates an empty tuple object when called without passing any arguments.

Using the not Operator

Code

# Python program to check if the tuple is empty using not in operator

# Creating an empty tuple
my_tuple = ()
# Using the 'not' operator
if not my_tuple:
    print ("The given tuple is empty")
else:
    print ("The given tuple is not empty")

# Printing our tuple
print(my_tuple)

Output:

The given tuple is empty
()
Using the len() Function

Code

# Python program to check if the tuple is empty using the length function

# Creating an empty tuple
my_tuple = ()

# Using len() function
len_tuple = len(my_tuple)

# Using the if-else Statements
if len_tuple == 0:
    print ("The given tuple is empty")
else:
    print ("The given tuple is not empty")

# Printing our tuple
print(my_tuple)

Output:

The given tuple is empty
()

An empty tuple called "my tuple" was initialized in the instance above. The length of the tuple was then determined using the built-in Python function len() and saved in the variable name "len_tuple." The length of my_tuple was then checked using an if statement to see if it equaled zero.

The tuple is considered empty if the condition stands true. The tuple is considered as not empty otherwise.

Changing a Tuple to Empty Tuple

Let's suppose we have a tuple that has elements in it. We need to change it to an empty tuple. Let us see how to do this.

Code

# Python program to see how to convert a tuple to an empty tuple

#creating a tuple
tuple_ = "a", 3, "b", "c", "d", "e", "g", "s", "k", "v", "l"
print("Original tuple: ", tuple_)

#tuples in Python are immutable objects; therefore, we cannot remove items from a tuple
#We can use merging of the tuples to remove an element from the tuple

tuple_ = tuple_[:4] + tuple_[5:]
print("After removing a single item:- ", tuple_)

# Method to remove all the elements from the tuple
#Converting our tuple into a Python List
list_ = list(tuple_) 

# Creating a for loop to delete all the elements of the list
for i in range(len(list_)):
  list_.pop()

#converting the list back to a tuple
tuple_ = tuple(list_)
print("New empty tuple:- ", tuple_)

Output:

Original tuple:  ('a', 3, 'b', 'c', 'd', 'e', 'g', 's', 'k', 'v', 'l')
After removing a single item:-  ('a', 3, 'b', 'c', 'e', 'g', 's', 'k', 'v', 'l')
New empty tuple:-  ()

Comparing with Another Empty Tuple

We will see the results if we compare two tuples

Code

# Python program to compare two tuples

# Creating an empty tuple
my_tuple = ( )

# Creating a second tuple
my_tuple1 = ('Python', 'Javatpoint')

# Comparing the tuples
if my_tuple == my_tuple1:
  print('my_tuple1 is empty')
else:
  print('my_tuple1 is not empty')

Output:
