Python – Unpack Tuple Items

Python Tuples in Python will allow you to store immutable objects. This article has listed the Packing and Unpacking of a Tuple.

Packing can be done by creating the tuple and providing a certain value to it. It has also explained the packing and unpacking of tuples with several examples.

What is Unpacking Tuple in Python?

Python consists of the tuple assignment feature which will assign the right-hand side of values to the left-hand side. This feature is known as the unpacking of the tuple of value into the variable. Let us look into the example below:

Example 1: Unpack the tuple in Python

# Define a tuple
my_tuple = (1, 2, 3)

# Unpack the tuple into separate variables
a, b, c = my_tuple

# Print the unpacked elements
print("Unpacked elements:")
print("a:", a)
print("b:", b)
print("c:", c)

Output

Unpacked elements:
a: 1
b: 2
c: 3

Example 2: Pack the Tuple in Python

Packing indicates the creation of a tuple and providing the values to it.

# Pack values into a tuple
my_tuple = (1, 2, 3)

# Print the tuple
print("Packed tuple:", my_tuple)

Output

Packed tuple: (1, 2, 3)

What are the examples of using Asterisk to the variable name in the tuple of Python?

An asterisk is used when the number of values is less than the number of values. An asterisk * is added to the variable name and the values will be given to the variable as a list.

# Define a tuple
my_tuple = (1, 2, 3, 4, 5)

# Unpack the tuple with an asterisk (*) for variable name
first, *middle, last = my_tuple

# Print the unpacked elements
print("First element:", first)
print("Middle elements:", middle)
print("Last element:", last)

Output

First element: 1
Middle elements: [2, 3, 4]
Last element: 5

Conclusion

In Python, unpacking tuple items is a straightforward way to assign individual values from a tuple to separate variables. It allows you to efficiently access and work with the elements of a tuple without needing to access them directly by index.

By using tuple unpacking, you can enhance code readability and make it more concise. It’s particularly useful when dealing with functions that return multiple values as tuples or when breaking down data structures like lists into their constituent parts.
