Talvez deva tentar algumas variações de ortografia:
placement program » placement problem (Expandir a busca), payment program (Expandir a busca), enhancement program (Expandir a busca)
desse placement » depth placement (Expandir a busca), nest placement (Expandir a busca), dis placement (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)
case desse » base desses (Expandir a busca), carne desse (Expandir a busca), case dossie (Expandir a busca)
node case » mode case (Expandir a busca), node base (Expandir a busca), nodule case (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( node case desse placement program ) OR ( python code python python programming ))~.
