Hello

I have below code to draw the circle, i want to add vertical line dividing the circle half and horizontal line and cross lines like in attached document. all the lines divide the circle equally with 45 degrees angle. I really appreciate the guidance

from turtle import *

r=100 ## radius of current circle

a=20 ## separation

circle(r)

## separation walk pen up

up()

left(90)

fd(a)

right(90) ## restoring direction

down()

r-=a

circle(r)
