How to Check if Tuple is Empty in Python

We can easily check if a tuple is empty in Python. An empty tuple has length 0, and is equal to False, so to check if a tuple is empty, we can just check one of these conditions.

empty_tuple = ()

#length check
if len(empty_tuple) == 0:
    print("Tuple is empty!")

#if statement check
if empty_tuple:
    print("Tuple is empty!")

#comparing to empty tuple
if empty_tuple == ():
    print("Tuple is empty!")

In Python, tuples are a collection of objects which are ordered and mutable. When working with tuples, it can be useful to be able to easily determine if the tuple is empty.

There are a few ways you can determine if a tuple is empty.

Of course, you can always test to see if the tuple is equal to another empty tuple. Second, the length of an empty tuple is 0. Finally, when converting an empty tuple to a boolean value, we get False.

In this case, we can use any one of these conditions to determine if a tuple is empty or not.

In the following Python code, you can see the three ways you ca check if a tuple is empty or not.

empty_tuple = ()

#length check
if len(empty_tuple) == 0:
    print("Tuple is empty!")

#if statement check
if empty_tuple:
    print("Tuple is empty!")

#comparing to empty tuple
if empty_tuple == ():
    print("Tuple is empty!")

Checking if Tuple is Empty with if Statement in Python

One fact we can use in Python to check if a tuple is empty is that a tuple that is empty is equivalent to the boolean value False.

In this case, we can test if a tuple is empty using a simple if statement.

empty_tuple = ()

#if statement check
if empty_tuple:
    print("Tuple is empty!")

Checking if Tuple is Empty Using Python len() Function

One of the ways we can easily check if a tuple is empty in Python is with the Python len() function.

The length of a tuple which is empty is 0.

Checking to see if a tuple is empty using the Python len() function is shown in the following Python code.

empty_tuple = ()

if len(empty_tuple) == 0:
    print("Tuple is empty!")

Checking if Tuple is Empty By Comparing to Another Empty Tuple in Python

You can also check if a tuple is empty by comparing it to another empty tuple. This is the most obvious method and works if you want to check if a list is empty, or check if a dictionary is empty.

Below is how to compare an empty tuple to another tuple to determine if the other tuple is empty or not.

empty_tuple = ()

if empty_tuple == ():
    print("Tuple is empty!")
