Why wouldn't the constant coordinatePoint need to be a var since it takes on a new value each time though the loop?

Wouldn't we we be reassigning coordinatePoint a new value each time around the loop? Each time we go around coordinatePoint takes on a new value and we then append said value into our accumulator array, results. FYI I'm a Python beginner. If this were coded in Python the variable coordinatePoint would be reassigned each time around the loop. So what is happening here!?! :)

struct Point { let x: Int let y: Int func points(inRange range: Int = 1) -> [Point] { var results = Point

    let lowerBondOfXRange = x - range
    let upperBoundOfXRange = x + range

    let lowerBoundOfYRange = y - range
    let upperBoundOfYRange = y + range

    for xCoordinate in lowerBondOfXRange...upperBoundOfXRange {
        for yCoordinate in lowerBoundOfYRange...upperBoundOfYRange {
            let coordinatePoint = Point(x: xCoordinate, y: yCoordinate)
            results.append(coordinatePoint)
        }
    }

    return results
}
