Talvez deva tentar algumas variações de ortografia:
modeling vpython » modeling method (Expandir a busca)
python program » action program (Expandir a busca)
using modeling » using model (Expandir a busca), using modern (Expandir a busca), using models (Expandir a busca)
vpython python » pythons python (Expandir a busca), piton python (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
cover with » covered with (Expandir a busca), fever with (Expandir a busca), river with (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( cover with python python program ) OR ( using modeling vpython python programming ))~.
