[Solved][Script Help] How does "while" loops actually work?

Hello , I started to write some python scripts and i just wondered how the loops actually work in a python script. I tried the code below. It works but it actually freezes the game scriptvise until the script is force-stopped.
import sims.sim_info

import sims4.commands

from objects.components.consumable_component import ConsumableComponent

import services

import re

import time



@sims4.commands.Command('updatebodytoggle', command_type=sims4.commands.CommandType.Live)

def updatebodytoggle(_connection=None):

output = sims4.commands.CheatOutput(_connection)

output("Trying...")

client = services.client_manager().get_first_client()

sim_info = client.active_sim.sim_info

while True:

sim_info._sim_ref().needs_fitness_update=True

sim_info.update_fitness_state()

output("Update Succesful")

time.sleep(1)
# I tried to cooldown first before restarting the loop but it didn't worked.
The code intends to update the active sim's body shape every 1 second (I may change this i'm just trying to understand how loops work)
Can someone help me about how to make loops without freezing the game scriptvise (If i need to give a example you get 10 simoleons every 1 minutes or etc. ). I think there is a another way instead doing it in commandline but i can't find it. Thanks in advance

(Sorry for bad grammar...)

The things i tried:
1-Making "while True" to "while 1=1" or defined some x to make it
2-Tried to make another function that runs the actual function

EDIT:
Using thread function in python library with "continue" and "breakout" functions are used to control the while loop without making other scripts stop or distrubted.

The code i achieved after doing it:

import sims.sim_info

import sims4.commands

from objects.components.consumable_component import ConsumableComponent

import services

import re

import time

import threading







@sims4.commands.Command('updatetoggle', command_type=sims4.commands.CommandType.Live)

def updateopen(_connection=None):

class ThreadingExample(object):

def __init__(self, interval=1):

self.interval = interval

thread = threading.Thread(target=self.run, args=())

thread.daemon = True # Daemonize thread

thread.start() # Start the execution

def run(self):

while True:

client = services.client_manager().get_first_client()

sim_info = client.active_sim.sim_info

sim_info._sim_ref().needs_fitness_update=True

sim_info.update_fitness_state()

time.sleep(1)
