Stopwatch in pygame

This article focus on creating a stopwatch using Tkinter in python
Tkinter : Tkinter is the standard GUI library for Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications. Tkinter provides a powerful object-oriented interface to the Tk GUI toolkit. Its very easy to get started with Tkinter, here are some sample codes to get your hands on Tkinter in python.




# Python program to create a
# a new window using Tkinter
# importing the required libraries
import tkinter
# creating a object 'top' as instance of class Tk
top = tkinter.Tk()
# This will start the blank window
top.mainloop()

Creating Stopwatch using Tkinter

Now lets try to create a program using Tkinter module to create a stopwatch.
A stopwatch is a handheld timepiece designed to measure the amount of time elapsed from a particular time when it is activated to the time when the piece is deactivated. A large digital version of a stopwatch designed for viewing at a distance, as in a sports stadium, is called a stop clock. In manual timing, the clock is started and stopped by a person pressing a button. In fully automatic time, both starting and stopping are triggered automatically, by sensors.
Required Modules: We are only going to use Tkinter for creating GUI and no other libraries will be used in this program.
Source Code:




# Python program to illustrate a stop watch
# using Tkinter
#importing the required libraries
import tkinter as Tkinter
from datetime import datetime
counter = 66600
running = False
def counter_label(label):
def count():
if running:
global counter
# To manage the initial delay.
if counter==66600:
display="Starting..."
else:
tt = datetime.fromtimestamp(counter)
string = tt.strftime("%H:%M:%S")
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 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()
f = Tkinter.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()
