Even if I want to rotate the snow flake it will only rotate once. Can someone help with this?

```
# For this level we need to a line fractal for the ground and a hexagonal snowflake made up of 6 line fractals. Check the guide for an image of the desired output.
def degreesToRadians(degrees):
# All vector operations require working in radians rather than degrees.
return Math.PI / 180 * degrees
# This function creates a line fractal. Read through it so you understand the recursive concept.
def line(start, end):
# First we need to get the full vector and its magnitude to determine if we are below our minimum threshold.
full = Vector.subtract(end, start)
distance = full.magnitude()
if distance < 4:
# If under our threshold distance, then we will simply draw a line along the vector and be done (the return tells us to exit the function).
hero.toggleFlowers(False)
hero.moveXY(start.x, start.y)
hero.toggleFlowers(True)
hero.moveXY(end.x, end.y)
return
# Otherwise we will create our fractal by getting a vector of half magnitude.
half = Vector.divide(full, 2)
# We will be creating 4 line fractals (start -> A, A -> B, B -> A, and A -> end) and so we need to calculate the intermediate positions A and B.
A = Vector.add(half, start)
# To get B, we need to rotate the vector half 90 degrees and multiply by 2/3 (so it is 1/3 of the original magnitude), then add this to A.
rotate = Vector.rotate(half, degreesToRadians(90))
rotate = Vector.multiply(rotate, 2 / 3)
B = Vector.add(rotate, A)
# Now just draw the 4 lines using the line functions.
line(start, A)
line(A, B)
line(B, A)
line(A, end)
def flake(start, end):
# To create a hexagonal flake we need to create 6 line fractals rotated by 60 degrees each time.
side = Vector.subtract(end, start)
a = start
b = end
for i in range(6):
line(a, b)
# To get the next edge, we need to rotate the side 60 degrees.
rotation = Vector.rotate(side, degreesToRadians(60))
# Now need to reset a and b with the beginning and end points for the new side.
a = b
b = Vector.add(rotation, b)
whiteXs = [Vector(12, 10), Vector(60, 10)]
redXs = [Vector(64, 52), Vector(52, 52)]
# You need to actually call the functions with a start and end vector for each.
line(Vector(12, 10),Vector(60, 10))
# Be sure to use actual Vector objectsâ€“simple objects will not work.
flake(redXs[0],redXs[1])
# Refresh often to avoid a memory leak and crash (working on it)
