Stopwatch code

[Vaishu7777]

Stop Watch code:

Python program to illustrate a stop watch

using Thinter

importing the required libraries

import tkinter as Tkinter

from datetime import datetime

counter 66000

running False

def counter label(label):

def count()

if running

global counter

To manage the initial delay.

if counter-66600:

display="Starting

else:

ttdatetime fromtimestamp(counter)

stringtt.strftime("SH:%M:NS")

display string

label['text'] display # Or label.config(text-display)

label.after(arg1, arg2) delays by

first argument given in milliseconds

and then calls the function given as second argument.

Generally like here we need to call the

function in which it is present repeatedly.

Delays by 1000ms 1 seconds and call count again. label.after(1000, count)

counter + 1

Triggering the start of the counter.

count()

start function of the stopwatch

def Start(label):

global running

running True

counter label(label)

start['state']='disabled'

stop['state']='normal"

reset['state']='normal'

Stop function of the stopwatch

def Stop():

global running

start['state']='normal" stop['state']='disabled'

reset['state']='normal"

running = False

Reset function of the stopwatch

def Reset(label):

global counter

counter-66600

If rest is pressed after pressing stop.

if running False:

reset['state']='disabled'

label['text']='Welcome!"

If If reset is pressed while the stopwatch is running.

else:

label['text']='Starting...!

root = Tkinter.Tk()

root.title("Stopwatch")

Fixing the window size.

root.minsize(width=250, height=70)

label = Tkinter.Label(root, text="Welcome!", fg="black", font="Verdana 30 bold")

label.pack() fTkinter.Frame(root)

start Tkinter Button(f, text="Start', width=6, command lambda:Start(label))

stop Tkinter Button(f, text='Stop', width=6, state='disabled', command-Stop)

reset = Tkinter.Button(f, text='Reset', width=6, state='disabled', command-lambda: Reset(label))

f.pack(anchor='center',pady-5)

start.pack(side="left")

stop.pack(side="left")

reset.pack(side="left")

root.mainloop()
