Incerasing number by every second +1 in Tkinter label

Question

My problem is, increasing numbers in while loop by every second. I have found the solution in shell, but "time.sleep()" function doesn't work on "Tkinter". Please help!

import time
from tkinter import *

root = Tk()
root.configure(background="grey")
root.geometry("500x500")

#I want to increase money in label every one second  +1  which is displayed,
Money = 100
etiket1 = Label(root,text = str(money)+"$",fg = "Green")
etiket1.pack()

while money < 300:
   money += 1
   time.sleep(1)
   if money == 300:
        break

#"while" loop doesn't work with "time.sleep()" in tkinter

root.mainloop()

You wouldn't normally want to be doing a sleep like that in a GUI program, but try this:

while money < 300:
    money += 1
    time.sleep(1)
    root.update()

root.after is the tkinter equivalent of time.sleep, except that time is milliseconds instead of seconds. There are multiple examples on SO to study.

import tkinter as tk
root = tk.Tk()

money = 100
label = tk.Label(root, text = str(money)+"$")
label.grid()

def countup(money):
    money += 1
    label['text'] = str(money)+"$"
    if money < 300:
        root.after(100, countup, money)

root.after(100, countup, money)
root.mainloop()
