Python - drawing a flower with turtle by recursive function

I am trying to draw a turtle-graphics flower with num petals. However, when I run my code I only get one single petal printed out. The error I get is under the def flower(num, i = 1) part of the code, but I am not sure how I can fix it.

import time
from turtle import *

pensize(2)
pencolor("orange")
bgcolor("green")
fillcolor("blue")
hideturtle()

def halfPetal():
    forward(50)
    left(30)
    forward(75)
    left(30)
    forward(50)
    left(120)

def petal():
    for i in range(2):
        halfPetal()

def flower(num, i=1):
    if i==1:
        begin_fill()
        for i in range(num):
            petal()
            left(360/petal())
        end_fill()

flower(12)
time.sleep(10)

At least one problem is at the line:

        left(360/petal())

petal does not return a value, so you're trying to divide by None. There is no such operation in Python, so you get a fatal error. Instead, I think you need to divide by the quantity of petals you're going to draw:

        left(360.0 / num)
