The start_new_thread() function included in the _thread module is used to create a new thread in the running program.
Syntax
_thread.start_new_thread ( function, args[, kwargs] )
This function starts a new thread and returns its identifier.
Parameters
-
function − Newly created thread starts running and calls the specified function. If any arguments are required for the function, that may be passed as parameters args and kwargs.
Example
import _thread import time # Define a function for the thread def thread_task( threadName, delay): for count in range(1, 6): time.sleep(delay) print ("Thread name: {} Count: {}".format ( threadName, count )) # Create two threads as follows try: _thread.start_new_thread( thread_task, ("Thread-1", 2, ) ) _thread.start_new_thread( thread_task, ("Thread-2", 4, ) ) except: print ("Error: unable to start thread") while True: pass
It will produce the following output −
Thread name: Thread-1 Count: 1 Thread name: Thread-2 Count: 1 Thread name: Thread-1 Count: 2 Thread name: Thread-1 Count: 3 Thread name: Thread-2 Count: 2 Thread name: Thread-1 Count: 4 Thread name: Thread-1 Count: 5 Thread name: Thread-2 Count: 3 Thread name: Thread-2 Count: 4 Thread name: Thread-2 Count: 5 Traceback (most recent call last): File "C:\Users\user\example.py", line 17, in <module> while True: KeyboardInterrupt
The program goes in an infinite loop. You will have to press "ctrl-c" to stop.
