The Walrus Operator - Advanced Python

The "walrus operator" in Python, denoted as `:=`, is a feature introduced in Python 3.8 that allows you to assign values to variables as part of an expression. It's particularly useful in situations where you want to assign a value to a variable and return it in a single expression, often making your code more concise and readable.

Example

Here's a simple example to demonstrate the use of the walrus operator:

numbers = [1, 2, 3, 4, 5] squared_numbers = [] for number in numbers:     squared = number ** 2     if squared > 5:         squared_numbers.append(squared)   # With the walrus operator squared_numbers = [] for number in numbers:     if (squared := number ** 2) > 5:         squared_numbers.append(squared)   print(squared_numbers)

In this example, `squared := number ** 2` is an instance of the walrus operator being used. It assigns the squared value of `number` to `squared` and checks if it is greater than 5 in the same line. 

This makes the code more concise by combining the assignment and comparison in a single line.
