This code draws a rotating sphere using the kandinsky module. It also uses the sleep function of the time module and sin(), cos() from the math module. Tested on the calculator using software version 23.2.6.

from math import *
import kandinsky
import time

def ellipse(xc, yc, w, h, N, angle):
  for i in range(N):
      x = w * sin(2 * pi* i / N)
      y = h * cos(2 * pi * i / N)
      xr = cos(angle) * x - sin(angle) * y
      yr = sin(angle) * x + cos(angle) * y
      xr += xc
      yr += yc
      kandinsky.set_pixel(int(xr), int(yr), "yellow")
for turns in range(2):
    angle_steps = 40
    np=100
    for a in range(angle_steps):
      angle = 2 * pi * a / angle_steps
      kandinsky.fill_rect(0,0,320,240,"black")
      for k in range(0, 120, 20):
        ellipse(160, 110, k, 100, np, angle)
      for k in range(0, 120, 20):
        ellipse(160, 110, 100, k, np, angle)
      time.sleep(0.2)
