Python Walrus Operator

The Walrus operator in Python is pretty straightforward. With it, you can assign a value to a variable and immediately use it. For example:

if (sum := 10+5) > 10:
    print("This should be printed)

In this example, the variable sum is assigned the value 15 and then we use it to evaluate if 15 > 10. As this is true, we should see the content of the print statement.

Be careful about the parenthesis! If we have something like this:

if sum := 10 + 5 > 10:
    print("Is this going to be printed?")

We will have the sum is equal to True and the print statement will be executed but the value of sum won't be 15.
