Thanks for the answer! i also modify the code a little bit to make it a little bit better

from datetime import datetime
from time import sleep


while True:
     now=datetime.now()
     current_time=now.strftime("%H:%M:%S")
     time=print("Current Time : ", current_time, end=\r)
     sleep(1)

You are currently creating the date-time object only once with the line. This means the time is only looked up once and then that value is stored in the variable.

now = datetime.now()
current_time = now.strftime("%H:%M:%S")

All you need to do is move those two lines into your loop. That way, the time is looked up on each loop iteration and you get new values. The modified code:

from datetime import datetime
import os
from time import sleep


def clear():
    os.system('cls')

while True:
    now = datetime.now()
    current_time = now.strftime("%H:%M:%S")
    time = print("Current Time =", current_time)
    sleep(1)
    clear()
