How do you do these two functions immediately?

[esther]

How am I supposed to perform these two functions? In fact, in this code, to perform the function while True immediately: 300 seconds without waiting.

time.sleep(300)
os.system('taskkill /f /im cmd.exe')
while True:
    print("It worked!")

If you don't use the streams, you can swam the expectation somehow.

import time
exec_time = time.perf_counter() + 5  # запуск через 5 секунд

while True:

print("It worked!")

time.sleep(1)

if exec_time and exec_time <= time.perf_counter():

exec_time = None

#os.system('taskkill /f /im cmd.exe')

print('taskkill /f /im cmd.exe')

It worked!

It worked!

It worked!

It worked!

It worked!

taskkill /f /im cmd.exe

It worked!

It worked!

It worked!
