Python Threading Parameters Issue

Question

I've been trying for around half an hour now and just cant seem to wrap my head around what im doing wrong here. Working Code:

import threading
from time import sleep


def printX():
    threading.Timer(5.0, printX).start()
    print("five")


printX()
while True:
    print("1")
    sleep(1)

This works, however I need to be able to dynamically assign what the print statement will be along with the delay. Desired Code:

import threading
from time import sleep


def printX(time, message):
    threading.Timer(int(time), printX).start()
    print(str(message)


printX(time, message)
while True:
    print("Rest of the program continues")
    sleep(1)

Thanks for any help in advance :).

Use the args argument: threading.Timer(time, printX, args=(time, message)).start() - — Jeronimo

threading.Timer could pass arguments with args:

threading.Timer(int(time), printX, (time, message)).start()

An alternative method is to define a class with printX as an inner function.

class thread:

    def __init__(self, time, message):
        self.time = time
        self.message = message

    def printX(self):
        threading.Timer(int(self.time), self.printX).start()
        print(str(self.message))

thread(3,"test message").printX()

while True:
    print("Rest of the program continues")
    sleep(1)
