If the variables are the same in number as the tuple value, then the value is automatically assigned to the left according to their position on the left. Python allows us to assign tuples of the variable on the left side of the assignment operator and tuple values on the right side. Let's have an example to understand how unpacking works in Python. Unpacking makes the code more readable that why it got popularity among Python developers. Unpacking - Unpacking is the term which refers to an operation list or tuple assigned to a single variable. Unpacking a Tuple in Python - Python offers immutable data types known as tuples. We can use any other name in place of args. Packing - As its name suggests, it wraps all the arguments into a single variable, and this function call gets into a tuple called args. Tuples can be used as keys if they contain only strings, numbers, or tuples if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. Below is the definition of the packing and unpacking arguments. Python developers called this process a tuple unpacking. Python tuple packing and unpacking can be useful when you pass multiple values between functions or assign multiple variables simultaneously. Each variable in the tuple can have one value (or more if use the * operator) from iterable on the right side of the assignment. Data Structures Python 3.7. These variables can be in the same number of tuple element. In Python, you can assign elements of a tuple or list to multiple variables. Python provides the facility to declare the variables on the left side of assignment operation. In Addition, we will also explore some practical examples for loops, function definition, and function calls. We will discuss how we can use iterable unpacking to make our code more readable. Hence, this feature generalized to all kinds of iterables nowadays, it is referred to as iterable unpacking. In the past, Python developers referred to this feature as tuple unpacking, but it became quite useful and popular among them. We need to pass five separate arguments to the function. Tuple unpacking is the ability within Python to take a tuple (or any other iterable) and unpack that iterable directly into one or more variables - it takes. Suppose we have a function that takes five arguments we create a list of five elements and pass it to the function, which will throw an error because elements are packed within the list. Now, once you understand tuples and how to create and access them, let’s see what unpacking a tuple means. Python provides a unique feature to pack or unpack the arguments. Printing the whole tuple ('a', 'b', 'c', 'd') First element of tuple a Slicing the tuple from 1st index element to 2nd index element ('b', 'c') Accessing last element of tuple d Unpacking the Tuples. In this tutorial, we will learn about the packing and unpacking of the arguments.
