.start()

The .start() method activates and prompts a thread object to be run.

thread_object.start()

Each thread_object can only be run once. Otherwise, a RuntimeError will be thrown.

import threading

def do_this():
  print("Task done!")

my_thread = threading.Thread(target=do_this)

my_thread.start()

After the .start() method is invoked against my_thread, the target function, do_this(), will execute and the following will be printed:

Task done!

Another example of the .start() method being used is shown below:
