I am trying to modify an attribute of a threaded function in the main python script from a function that has been imported from an external module.
I get this error : NameError: global name 'some_thread' is not defined
My intention is to move some functions out of the maincode.py file to the subcode.py file in order to clean up the maincode.py file and use the subcode.py file as a module. I don't know what the right way is to do setattr() from the imported module to a threaded function in the mainfile.py , nor do i know if that is even a good idea.
