How to clear the list every interval of time?

Question

Python

Good night everybody!
I'm trying to understand how it's possible to clear the list by timer...
Numbers are written to the list every two seconds...
I want to delete (list.clear()) the contents of the list every 15 seconds.
I can't figure out how to do it. Help plz.

time_count=2

a=[]
b=0
while True:

    for i in range(time_count):
        sleep(1)
        
    b += 1
    a.append(b)

    print( "a:",a)

I answered in the comments, please close the question

import time
my_list = []
data = 12
add_timer = int(time.time())
clear_timer = int(time.time())

while True:
    if int(time.time()) - clear_timer >= 15:
        clear_timer = int(time.time())
        my_list.clear() # Очищаем список каждые 15 сек
        print('Удаляем')
    if int(time.time()) - add_timer >= 2:
        add_timer = int(time.time())
        my_list.append(data) # Записываем числа в список каждые 2 сек
        print('Записываем')
