I'm a little confused... Please explain! [SOLVED]

So we have this code below.

    def __init__(self, model, year, make="Toyota"):
        self.make = make
        self.model = model
        self.year = year
        self.is_moving = False

    def stop(self):
        if self.is_moving:
            print("The car stopped")
            self.is_moving = False
        else:
            print("The car has already stopped")

    def go(self, speed):
        if not self.is_moving:
            print("The car starts moving")
            self.is_moving = True
        print(f"The car is going {speed}")

The is_moving is set to False but when we use it in the go() method we check to see if it's True with an if statement 'if not self.is_moving:' then we will set it to True. Its Set to False though so that code shouldn't run. So how does the if statement run if its set to False?

I think I figured it out. It's because we are checking not is_moving, which means if it is False then run the following code and set is_moving to True. Is that correct?
