How to use multiple threads

Question

I have this code:

import thread

def print_out(m1, m2):
    print m1
    print m2
    print \"\\n\"

for num in range(0, 10):
    thread.start_new_thread(print_o         


        

Answer 1

Whenever you are creating thread you need to run main thread before that. Here you are not running any main tread.

To solve the problem you can add a print statement of any other statement. Lets modify your code

import thread
import time

def print_out(m1, m2):
    print m1
    print m2
    print "\n"

for num in range(0, 10):
    thread.start_new_thread(print_out, ('a', 'b'))
    time.sleep(.1)

Here time.sleep() is creating main tread for you and thread.start_new_thread creating 10 threads on the main tread. Note: You can add any statement in place of time.sleep()
