He cambiado algo de código en el código swapnil-jariwala para hacer un pequeño reloj de consola.
from threading import Timer, Thread, Event
from datetime import datetime
class PT():
def __init__(self, t, hFunction):
self.t = t
self.hFunction = hFunction
self.thread = Timer(self.t, self.handle_function)
def handle_function(self):
self.hFunction()
self.thread = Timer(self.t, self.handle_function)
self.thread.start()
def start(self):
self.thread.start()
def printer():
tempo = datetime.today()
h,m,s = tempo.hour, tempo.minute, tempo.second
print(f"{h}:{m}:{s}")
t = PT(1, printer)
t.start()

Temporizador con interfaz gráfica tkinter
Este código coloca el temporizador del reloj en una pequeña ventana con tkinter
from threading import Timer, Thread, Event
from datetime import datetime
import tkinter as tk
app = tk.Tk()
lab = tk.Label(app, text="Timer will start in a sec")
lab.pack()
class perpetualTimer():
def __init__(self, t, hFunction):
self.t = t
self.hFunction = hFunction
self.thread = Timer(self.t, self.handle_function)
def handle_function(self):
self.hFunction()
self.thread = Timer(self.t, self.handle_function)
self.thread.start()
def start(self):
self.thread.start()
def cancel(self):
self.thread.cancel()
def printer():
tempo = datetime.today()
clock = "{}:{}:{}".format(tempo.hour, tempo.minute, tempo.second)
try:
lab['text'] = clock
except RuntimeError:
exit()
t = perpetualTimer(1, printer)
t.start()
app.mainloop()
