Talvez deva tentar algumas variações de ortografia:
decrease based » decreased base (Expandir a busca), decrease blood (Expandir a busca)
vpython codigo » python codigo (Expandir a busca), python coding (Expandir a busca), vpython colisoes (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
on decrease » on decreased (Expandir a busca), of decrease (Expandir a busca), or decrease (Expandir a busca)
code on » code of (Expandir a busca), code and (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code on decrease based program ) OR ( vpython codigo python python programming ))~.
