 # The geometry of flowers

it keeps on saying that my move xy requires 2 numbers

``````def drawCircle(x, y, size):
angle = 0
hero.toggleFlowers(False)
while angle <= Math.PI * 2:
newX = x + (size * Math.cos(angle))
newY = y + (size * Math.sin(angle))
hero.moveXY(newX, newY)
hero.toggleFlowers(True)
angle += 0.2
``````

Thanks

You need to put inputs into the brackets of the function, otherwise there aren’t any inputs.

what do you mean by inputs?

Things which go into the function.
e.g. findEnemy(enemies)
enemies is the input.

ok i’ll try that(20chararcters)

I think you should maybe review older function levels because you don’t seem to understand them.
Let me try to explain:
The function `drawCircle(x, y, size)` has three inputs: x, y, and size. That means you need to put three values in, otherwise your code sill have nowhere to move to because when you define NewX and NewY it uses the variables which you put in the brackets of the function. Therefore because you haven’t put any in, it doesn’t work. Hence the error.
Try putting three variables in the function. The X, Y, and the Size. You’ve only put in the size.
To give you a hint I’ll show you what a three input function might look like with inputs:

``````# first you define it
def drawSquare(x, y, size):
# code goes here....
pass

# then call (use) the function
drawSquare(30, 46, 10)

``````

Remember! “The order you put the values in the brackets of the function matters, you couldn’t do the size first, then the x and y. Unless you changed it when you defined it.”
Do you get it more now?

thank you I re-read what you said three times and I understood
