Class project drawing with code for my web development course:

import turtle

def draw_square(some_turtle):
for i in range (1,5):

def draw_stem():
stem = turtle.Turtle()

def draw_petals():
window = turtle.Screen()

max = turtle.Turtle()
for i in range(1,37):
draw_square(max)


draw_stem()
draw_petals()
