If you're new to this then I'd suggest skipping the Python part and
instead making a graphical model using Processing tools to do what you
want. The visual aspect of making models will help guide you through
the process, and there's plently of video tutorials on Youtube showing
how to do this.

You can even then take the model and automatically convert it directly
to a Python script with a single button click!

Hope that helps,
