Create an Empty Tuple in Python

Tuple is one of the data structures of the Python programming language. It is used to store multiple values separated by commas in an ordered manner.

It is immutable in the sense that once the tuple is created cannot perform any operations like deleting, appending, etc. The elements in the tuple can be int, float, string, or binary data types, and it allows duplicates of the elements. It uses indexing for accessing the elements. It allows a single element to be in a tuple.

There are different ways to create the empty tuple. Let's see each way in detail.

• braces()

• tuple keyword

Creating an Empty Tuple using braces() 

The empty tuple can be created using the braces().

Syntax

The following is the syntax.

variable_name = ()

Where,

• Variable_name is the name of the tuple

• () is the symbol for creating the empty tuple

Example

As you can observe in the following example, when we assign the braces "()" to a variable, an empty tuple will be created.

tuple1 = ()
print("The empty tuple created using brackets: ",tuple1)
print(type(tuple1))

Following is an output of the above code -

The empty tuple created using brackets:  ()
<class 'tuple'>

Example

In this example, we have created an empty tuple using the braces. Since the tuple in Python is immutable, when we try to append values to it, it will generate an error.

tuple1 = ()
print("The empty tuple created using brackets: ",tuple1)
tuple1[0] = 10
print(type(tuple1))

Following is an output of the above code -

('The empty tuple created using brackets: ', ())
Traceback (most recent call last):
  File "main.py", line 3, in <module>
    tuple1[0] = 10
TypeError: 'tuple' object does not support item assignment

Creating an Empty tuple using tuple() Function

The empty tuple can be created using the tuple() function available in Python.

Syntax

The syntax is as follows.

variable_name = tuple()

Where,

• varibale_name is the name of the tuple

• tuple is the keyword for creating the empty tuple

Example

Here, when we assign the function tuple() to a variable an empty tuple will be created.

tuple1 = tuple()
print("The empty tuple created using brackets, ",tuple1)
print(type(tuple1))

Following is an output of the above code -

The empty tuple created using brackets,  ()
<class 'tuple'>

Example

In this example, we created the tuple using the tuple keyword function, and when we try to append an element, it will raise an error as the tuple is immutable.

tuple1 = tuple()
print("The empty tuple created using brackets, ",tuple1)
tuple1[0] = "Niharika"
print(type(tuple1))

The following is the output of the empty tuple created using the tuple keyword.

('The empty tuple created using brackets, ', ())
Traceback (most recent call last):
  File "main.py", line 3, in <module>
    tuple1[0] = "Niharika"
TypeError: 'tuple' object does not support item assignment
