Run two functions parallel in While True Loop

Question

I have made a Cookie Clicker game on Python and am trying to get two functions to run in parallel while in an infinite loop.

I need them to be in parallel, since I want one of them to add one to a variable every second and the other one to add one to another variable every ten seconds. I do this by just using time.sleep(), but if I use the same loop for both, it's just gonna run the first function, wait 1s then add one and then wait 10s and add another one.

Does anyone know a way around this?

def farm():
   time.sleep(random.choice(range(1, 3)))`
   x += 1

def automatic():
   time.sleep(random.choice(range(1, 10)))
   y += 1

while True:
   farm()
   automatic()

This is my code kinda simplified

I tried using two different threads from the threading library, but that started crashing.

Instead of using threading, you can move your sleep outside of each function and check in each cycle if relevant function should trigger.

import time, random

def farm():
    print("farm")

def automatic():
    print("automatic")

next_farm = random.choice(range(1, 3))
next_automatic = random.choice(range(1, 10))
    
while True:
    if next_farm > 0:
        next_farm -= 1
    else:
        farm()
        next_farm = random.choice(range(1, 3))

    if next_automatic > 0:
        next_automatic -= 1
    else:
        automatic()
        next_automatic = random.choice(range(1, 10))

    time.sleep(1)
