Talvez deva tentar algumas variações de ortografia:
basic function » basic functions (Expandir a busca), basis function (Expandir a busca), basis functions (Expandir a busca)
function virus » function versus (Expandir a busca), function values (Expandir a busca), function visual (Expandir a busca)
virus decrease » virus decreases (Expandir a busca), virus increase (Expandir a busca), virus disease (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code basic » code based (Expandir a busca), some basic (Expandir a busca), care basic (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code basic function virus decrease ) OR ( _ python python python programming ))~.
