What happened to thread.start_new_thread in python 3
Question:
I liked the ability to turn a function into a thread without the unnecessary line to define a class. I know about _thread, however it appears that you are not supposed to use _thread. Is there a good-practice equivalent of thread.start_new_thread for python 3?
Answers:
threading.Thread(target=some_callable_function).start()
or if you wish to pass arguments,
threading.Thread(target=some_callable_function,
args=(tuple, of, args),
kwargs={'dict': 'of', 'keyword': 'args'},
).start()
Unfortunately there is not a direct equivalent, because Python 3 is meant to be more portable than Python 2 and the _thread interface is seen as too low-level for this purpose.
In Python 3 the best practice is usually to use threading.Thread(target=f...). This uses different semantics, but is preferred because the interface is easier to port to other Python implementations.
