thread_subclass.py

## To use threads you need import Thread using the following code:
from threading import Thread

##Also we use the sleep function to make the thread "sleep" 
from time import sleep

## To create a thread in Python you'll want to make your class work as a thread.
## For this, you should subclass your class from the Thread class
class tryThread(Thread):
    def __init__(self):
        Thread.__init__(self)
        self.message = "Hello Parallel Thread!!\n"

##this method thod prints only the message 
    def print_message(self):
        print (self.message)

##The run method prints ten times the message 
    def run(self):
        print ("Thread Starting\n")
        x=0
        while (x < 10):
            self.print_message()
            sleep(2)
            x += 1
        print ("Thread Ended\n")


#start the main process
print ("Process Started")

# create an instance of the HelloWorld class
hello_Python = tryThread()

# print the message...starting the thread
hello_Python.start()

#end the main process
print ("Process Ended")
