Introduction
Walrus Operator — it is another name for assignment expressions. According to the official documentation, this is the way to assign variables in an expression using the NAME: = expr notation. Assignment expressions allow you to assign a value to a variable, even to a variable that does not yet exist, in the context of the expression, rather than as a separate statement.
Code :

Output:

Here, instead of using "len (a)" in two places, we assigned it to the variable "n", which can be used later. This helps us eliminate code duplication and improve readability.
Example —
Let’s try to understand the assignment expressions more clearly with an example using both Python 3.7 and Python 3.8. Here we have a list of dictionaries named "sample_data" that contains userId, name, and a boolean named complete.
