Talvez deva tentar algumas variações de ortografia:
reference active » reference acte (Expandir a busca), reference adaptive (Expandir a busca), referencia activa (Expandir a busca)
coder reference » modern reference (Expandir a busca), model reference (Expandir a busca), mode reference (Expandir a busca)
active program » action program (Expandir a busca), activity program (Expandir a busca), practice program (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (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 reference active program ) OR ( in python python python programming ))~.
