Talvez deva tentar algumas variações de ortografia:
efficacy coding » efficacy according (Expandir a busca), efficacy during (Expandir a busca), efficacy dacing (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
its efficacy » its efficiency (Expandir a busca), and efficacy (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
coder its » code its (Expandir a busca), power its (Expandir a busca), over its (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder its efficacy coding ) OR ( in python python python programming ))~.
