Talvez deva tentar algumas variações de ortografia:
efficient python » efficient method (Expandir a busca), efficient action (Expandir a busca), efficient methods (Expandir a busca)
java programming » and programming (Expandir a busca), based programming (Expandir a busca), goal programming (Expandir a busca)
the efficient » the efficiency (Expandir a busca), an efficient (Expandir a busca), _ efficient (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
python java » python data (Expandir a busca), python capaz (Expandir a busca)
python the » python to (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder python java programming ) OR ( python the efficient python programming ))~.
