2,004 Points'if not' question.
does 'if self.is_moving:' also translate as 'if self.is_moving == False'? if so does that mean 'if not self.is_moving:' means 'if self.is_moving == True:'?
if this is correct why does the go(self, speed) method print when the is_moving value is False

The car uses 50 fuel each time you use gas and only has 50 fuel to start with. Note the part about use_gas().
You may want to rewrite the code a bit to make it more realistic. For example, you might want to write get_fuel() where you can accept so much gas based on how much you have in your tank.

In other words, it would be equivalent if self.is_moving == True:

2,004 Pointsthanks, could you explain why both methods in the video run when the if statements are asking for two different things? self.is_moving = False, so why does it run in both 'if self.is_moving:' and 'if not self.is_moving:'?
