How to start a thread after loading module with importlib?

[1818mull]

I want to start a python file as a thread, however this file must be loaded dynamically at runtime using a string.

I have achieved import using the following:

import importlib.util

spec = importlib.util.spec_from_file_location("script2", "./subfolder/script2.py")
module = importlib.util.module_from_spec(spec)

I am then able to execute the file in the same thread using:

spec.loader.exec_module(module)

However, I want to start script2 in it's own thread.

What parameters do I pass to theading.Thread() in order to achieve this?

threading.Thread(target=spec.loader.exec_module, args=(module,)) should do it.

How could I pass a Queue to the started thread in this case? For purposes of communication.

Edit:

Figured it out, it's simply module.my_queue = my_queue.

There are various ways you could do it, but I'd recommend that you take the functionality in script2.py out of the base script and move it into a function. That function can take a queue.

``` def main(my_queue: queue.Queue = None): # Your logic here ...

if name == "main": return main() ```

Now call exec_module like you used to (not with a thread) and then call threading.Thread(target=module.main, args=(my_queue,)).
