Why isn't working properly??

Question

Taks:
Write a code to print the no of seconds you have logged when you hit the enter
Here's my try:
import threading
import time
def func():
cou=0
while True:
time.sleep(1)
cou=cou+1
print(f"you have logged for {cou} secs")
t = threading.Thread(target=func,daemon=True)
t.start()
p = input("Enter the enter:")

Answer 1

Yes show me the code

Answer 2

Why we need to define "cou" as global variable?
