Perhaps you should try some spelling variations:
efficient programming » efficient processing (Expand search), fragment programming (Expand search)
decrease efficient » decrease coefficient (Expand search), increase efficiency (Expand search), increased efficiency (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
python code » python coding (Expand search), python redes (Expand search)
code python » codigo python (Expand search), pacote python (Expand search)

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

• Removing quotes may allow a broader search: (( code to decrease efficient programming ) OR ( python code python python programming ))~.
