Talvez deva tentar algumas variações de ortografia:
decrease placement » decreased platelet (Expandir a busca), desse placement (Expandir a busca)
placement program » placement problem (Expandir a busca), payment program (Expandir a busca), enhancement program (Expandir a busca)
python codigo » python coding (Expandir a busca), python code (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
set decrease » stent decrease (Expandir a busca), not decrease (Expandir a busca), use decrease (Expandir a busca)
code set » code art (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code set decrease placement program ) OR ( python codigo python python programming ))~.
