Talvez deva tentar algumas variações de ortografia:
cobol programming » robot programming (Expandir a busca), robots programming (Expandir a busca), goal programming (Expandir a busca)
vpython python » python python (Expandir a busca), pythons python (Expandir a busca), piton python (Expandir a busca)
powder method » power method (Expandir a busca)
coder powder » copper powder (Expandir a busca), over powder (Expandir a busca), copper powders (Expandir a busca)
method cobol » method cook (Expandir a busca), method control (Expandir a busca), method cost (Expandir a busca)
code vpython » 3d vpython (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder powder method cobol programming ) OR ( python code vpython python programming ))~.
