Talvez deva tentar algumas variações de ortografia:
ratio programming » radio programming (Expandir a busca), creation programming (Expandir a busca), to programming (Expandir a busca)
coder diameter » core diameter (Expandir a busca), collar diameter (Expandir a busca), fiber diameter (Expandir a busca)
diameter ratio » parameter ratio (Expandir a busca), diameter at (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 diameter ratio programming ) OR ( in python python python programming ))~.
