how to trigger a function via another function

Question

i am making an app with Tkinter and need to trigger a function using another:

import pynput
import datetime
import tkinter
from tkinter import *
import pyautogui
import time
from pynput.keyboard import Key, Controller
win = Tk()
win.title('autoclass.enter V1')
win.geometry('500x500')

coord1= Entry(win, width=30)
coord1.place(x=178, y=120)
coord2= Entry(win, width=30)
coord2.place(x=178, y=155)
tempo= Entry(win, width=30)
tempo.place(x=178, y=207)
chat1= Entry(win, width=30)
chat1.place(x=178, y=254)
chat2= Entry(win, width=30)
chat2.place(x=178, y=280)
agora= Entry(win, width=30)
agora.place(x=178, y=320)



 def chronus():
    agora = hora.get()
    now = (datetime.datetime.now())
    if agora == now:
    
    else:

def start():
    time.sleep(2)
    b = coord2.get()
    c = coord1.get()
    d = int(c,0)
    e = int(b,0)

    f = tempo.get()
    g = int(f,0)
    h = (g * 60)

    i = chat1.get()
    j = chat2.get()
    k = int(i,0)
    l = int(j,0)


    pyautogui.click(d, e)
    time.sleep(g)
    pyautogui.moveTo(k, l, duration = 1) 
    pyautogui.click(k, l) 
    keyboard = Controller()
    time.sleep(2)
    time.sleep(8)
    keyboard.type(name.get())
    keyboard.press(Key.enter)
    keyboard.release(Key.enter)
[...]

the function chronus() need to trigger the start() when the time indicated is the same as the time the clock is, but how to make one trigger the other?

Answer 1

def start():
    print("oi")

def chronus():
    agora = hora.get()
    now = (datetime.datetime.now())
    if agora == now:
        start()
    else:

It usually works that way.
