First we add a new attribute to our class which will store the return value. (This is done in the init function, calledself._return) Secondly, we make a change to the defaultrun()method (which is called internally by Thread) to store the return value from our target function into our ...

I am using the Python API and I want to redirect the output of an asynchronously called function without return value. Is this maybe impossible? My Python Script looks a little bit like this: importmatlab.engine as eng importStringIO
