How threading.timer works in python [duplicate]

Question

I want to run a function every n seconds. After some research, I figured out this code:

import threading

def print_hello():
    threading.Timer(5.0, print_hello).start()
    print("hello")

print_hello()

Will a new thread be created every 5 sec when print_hello() is called?

Answer 1

Timer is a thread. Its created when you instantiate Timer(). That thread waits the given amount of time then calls the function. Since the function creates a new timer, yes, it is called every 5 seconds.
