Can't control Tello through Python

[stoop]

i am having a hard time trying to control Tello via Python on a variety of PC and Mac machines. I connect OK to the drone's WiFi but running the code gives me errrors. I'm using the djitellopy library - here is the simple code I am trying:

from djitellopy import tello
from time import sleep

drone = tello.Tello()
drone.connect()
sleep(5)

print(drone.get_battery())
drone.takeoff()
sleep(3)
drone.rotate_clockwise(90)
sleep(3)
drone.land()

And here is the output from my Mac. Could it be the Python version?

PS: Flies just fine using my iPhone as controller

Something prevents the library from listening on port 8890.

Sounds similar to to this issue: Connection Issue - Did not receive a state packet from the Tello - githubmemory

In that case, using Python 3.8 on MacOS helped.

I know this is ancient, but it looks like all the sample code was written for Python 2.7. I had installed Python 3 thinking newer is better, but none of the sample code worked until I installed Python2.7.11 separately.
