How to use a thread in a subclass

To implement a new thread using the threading module, you have to do the following:

• Define a new subclass of the Thread class

• Override the _init__(self [,args]) method to add additional arguments

• Then, you need to override the run(self [,args]) method to implement what the thread should do when it is started

Once you have created the new Thread subclass, you can create an instance of it and then start a new thread by invoking the start() method, which will, in turn, call the run() method.

How to do it…

To implement a thread in a subclass, we define the myThread class. It has two methods that must be overridden with the thread's arguments:

import threading
import time

exitFlag = 0

class myThread (threading.Thread):
    def __init__(self, threadID, name, counter):
        threading.Thread.__init__(self)
        self.threadID = threadID
        self.name = name
        self.counter = counter
    def run(self):
        print ("Starting " + self.name)
        print_time...
