Talvez deva tentar algumas variações de ortografia:
vpython programming » method programming (Expandir a busca), creation programming (Expandir a busca)
modeling vpython » modeling method (Expandir a busca)
sector modeling » reactor modeling (Expandir a busca), section modeling (Expandir a busca), sensor modeling (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder sector » power sector (Expandir a busca), modern sectors (Expandir a busca), flower sector (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 sector modeling vpython programming ) OR ( in python python python programming ))~.
