Practical example of thread using Python

The practical application

Threads are really amazing concept to learn and useful too…as we know that multi-tasking is the need of every software.i have created a small program in python to show use of threads

• its a simple GUI Tkinter based app

simple GUI

The first button will print numbers within a range and with second button we can change color to a specified color while first task is being executed

first we need to import all required libraries

from tkinter import *
import threading
import time

and then creating a simple frame

root =Tk()
root.title(‘example’)
root.geometry(“400x300+600+100”)

here we need to create two thread for performing two different operations

creating two classes for two threads

class t1(threading.Thread):
     def run(self):
         print("entering into thread")
         for i in range(1,20):
               print(i)
                time.sleep(1)
obj1 = t1()
btn = Button(root,text="click me to start first  thread",command=obj1.start)
class t2(threading.Thread):
    def run(self):
        root.configure(background='darkslateblue')
obj2 = t2()
btn1 = Button(root,text="start second thread",command=obj2.start)
btn.pack()
btn1.pack()

root.mainloop()
