Walrus operator does an inline assignment to a variable and resolves to the value assigned. If it is in a condition statement, like “if x := y:”, it assigns the value of y to x then interprets the expression of the condition as of it just said “if x:”. Functionally, that means the assignment happens regardless of the value of y, but the condition only passes if the value of y is “truthy”, i.e. if it’s not None, an empty collection, numerically equal to zero, or just False.
