How to Multithread this task in Python?

Question

currently I'm working on a Whatsapp bot. He's working perfect, but now I wanted to expand him with threads. Unfortunately, something is not working. I watched many videos to find a solution however I didn't get it. Thank you for all your help!! Here is my code:

import threading
import time


from selenium.webdriver.common.keys import Keys
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions
from selenium.webdriver.common.by import By


def execute(amount, adressed, message):
    profile_path = "user-data-dir=/home/daniel/.config/google-chrome/storing"

    options = webdriver.ChromeOptions()
    options.add_argument(profile_path)
    browser = webdriver.Chrome(executable_path="./chromedriver", options=options)
    browser.get("https://web.whatsapp.com")

    time.sleep(5)
    search = WebDriverWait(browser, 500).until(expected_conditions.presence_of_element_located((By.CSS_SELECTOR, "#side > div.SgIJV > div > label > div > div._2_1wd.copyable-text.selectable-text")))
    search.send_keys(adressed)
    time.sleep(1)
    search.send_keys(Keys.ENTER)
    send = WebDriverWait(browser, 500).until(expected_conditions.presence_of_element_located((By.CSS_SELECTOR,
                                                                                              "#main > footer > div.vR1LG._3wXwX.copyable-area > div._2A8P4._2A1WX > div > div._2_1wd.copyable-text.selectable-text")))

    for i in range(amount):
        send.send_keys(message)
        send.send_keys(Keys.ENTER)

moin = (1000, 'Hyhf', 'Hallo')

threads = []
for _ in range(2):
    f1 = threading.Thread(target=execute, args=moin)
    f1.start()
    threads.append(f1)

for thread in threads:
    thread.join()

It starts both, but just on ist affected by the code: enter image description here

Here is the error-code:

I think the arguments on this line

f1 = threading.Thread(target=execute, args=moin)

needs to look like this

f1 = threading.Thread(target=execute, args=(moin,))

Can you share the errors you get when running the code? – JMad Apr 09 '21 at 17:36
Yes, I will add it in the question – Apr 09 '21 at 18:04
Ok, looking at the error i would recommend looking at this https://stackoverflow.com/a/60048564/11078962 – JMad Apr 09 '21 at 18:08
