Empty Tuple Python

What are Tuples in Python?

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

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

Output:

 () () 

Explanation:

• In the first step, a new tuple, T1, is created without putting anything within parentheses with respect to the empty tuple. As a consequence of this, you get an empty tuple which has no elements.
• In the second step, an empty tuple T2 is formed using the 'tuple()' This constructor, on being called with no arguments, would return an empty tuple.
• Both the methods return the same result, showing two approaches of an empty tuple construction in Python language.

1. 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

Output:

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

Explanation:

• In this example code:
• An empty tuple entitled 'my_tuple' is named.
• The 'not' Operator is applied to 'my_tuple' is to determine if it is 'False' in a boolean context, which means that 'my_tuple' is empty.
• If the 'my_tuple' has no items ('my_tuple' evaluates to 'True'), a message announcing "The given tuple is empty" will be shown. In contrast to it, the message "The given tuple is not empty" is displayed.
• So, the tuple 'my_tuple' is printed again to check its contents, and in this case, the 'tuple ()' will be empty.

Code

Output:

 The given tuple is empty () 

Explanation:

• In this program:
• A tuple named 'my_tuple' with an empty list is set up.
• The `len()` function is the one that is used to get the length of the tuple, which in this case will be '0' for an empty tuple.
• The program uses an if-else statement to check for the equality of the length of the tuple ('len_tuple') to zero. If it is, it prints "The given tuple is empty"; otherwise, it prints "The given tuple is not empty".
• The last step here is that 'my_tuple' is printed to verify its content, which will be empty 'tuple ()' in this case.

2. 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

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:- () 

Explanation:

• In this example code:
• An original tuple named 'tuple_' is defined(or constructed) with some items.
• To practice removing a single element from the tuple, a new tuple is created by joining the sequences of the original tuple. This makes the tuple lose the element in position 4 (the fifth element pops out).
• After that, the elements of the list are unpacked into a tuple, which is an empty one. This will be accomplished using the 'list()'
• The 'For' loop runs the entire length of the list by using 'pop()' to remove all elements from the list.
• The result is then converted into an empty tuple using the tuple '''' function, which uses the 'tuple()'
• When we execute this line, the empty tuple is printed in response to confirm its contents.

Though tuples are immutable, that is, there is no way of removing its elements instantly, you can do the same by creating a new tuple but with some excluded elements. And another technique is that we can first convert tuples to lists and, then, perform any operation on them, and finally convert them again to tuples to get the desired result.

Comparing with Another Empty Tuple

We will see the results if we compare two tuples

Code

Output:

 my_tuple1 is not empty 

Explanation:

• A tuple named 'my_tuple' is created as an empty tuple.
• We can use another tuple named my_tuple is created with two elements python and javatpoint.
• The program afterward, uses 'my_tuple' and 'my_tuple1' to compare them using the '==' operator.
• As "my_tuple" is an empty tuple and "my_tuple1" is not, the condition "my_tuple == my_tuple1" evaluates as False ('my_tuple == my_tuple1').
• The program in the end outputs 'my_tuple1 is not empty'.
• The following program shows the elementary comparison of two tuples in Python. The outcome of the provided comparison depends on the elements contained in the tuples.
