Perhaps you should try some spelling variations:
propositions python » propositions on (Expand search), propositions to (Expand search), propositions that (Expand search)
based propositions » cases propositions (Expand search), and propositions (Expand search), based compositions (Expand search)
decoder codec » decoder codecs (Expand search), decoder model (Expand search), decoder models (Expand search)
python codigo » python coding (Expand search), python code (Expand search)
codec python » logic python (Expand search)
python based » action based (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decoder codec python codigo python ) OR ( python based propositions python programming ))~.
