Talvez deva tentar algumas variações de ortografia:
affect efficiency » effect efficiency (Expandir a busca), effect efficient (Expandir a busca), effluent efficiency (Expandir a busca)
efficiency coding » efficiency cooling (Expandir a busca), efficient coding (Expandir a busca), efficiency according (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder affect » cover affect (Expandir a busca), order affect (Expandir a busca), color affect (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (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 affect efficiency coding ) OR ( in python python python programming ))~.
