Every Python program has at least one thread of execution called the main thread. The main thread by default is a non-daemon thread.

Sometimes we may need to create additional threads in our program in order to execute the code concurrently.

Here is the syntax for creating a new thread −

object = threading.Thread(target, daemon)

The Thread() constructor creates a new object. By calling the start() method, the new thread starts running, and it calls automatically a function given as argument to target parameter which defaults to run. The second parameter is "daemon" which is by default None.

Example

from time import sleep from threading import current_thread from threading import Thread # function to be executed by a new thread def run(): # get the current thread thread = current_thread() # is it a daemon thread? print(f'Daemon thread: {thread.daemon}') # create a new thread thread = Thread(target=run) # start the new thread thread.start() # block for a 0.5 sec sleep(0.5)

It will produce the following output −

Daemon thread: False

So, creating a thread by the following statement −

t1=threading.Thread(target=run)

This statement creates a non-daemon thread. When started, it calls the run() method.
