Talvez deva tentar algumas variações de ortografia:
model vpython » modeling vpython (Expandir a busca), modulo python (Expandir a busca)
data decrease » rate decrease (Expandir a busca), data increase (Expandir a busca), ratio decrease (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coding model » coding mode (Expandir a busca), costing model (Expandir a busca), folding model (Expandir a busca)
vpython data » python data (Expandir a busca)
of python » _ python (Expandir a busca), in python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coding model vpython data decrease ) OR ( of python python python programming ))~.
