Talvez deva tentar algumas variações de ortografia:
vpython programming » method programming (Expandir a busca), creation programming (Expandir a busca)
reference gate » reference rate (Expandir a busca), reference state (Expandir a busca), reference grade (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)
code vpython » 3d vpython (Expandir a busca)
piton python » pitons python (Expandir a busca), in python (Expandir a busca), with python (Expandir a busca)
gate piton » gate python (Expandir a busca), jane piton (Expandir a busca), gates hilton (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder python code vpython programming ) OR ( reference gate piton python programming ))*.
