Talvez deva tentar algumas variações de ortografia:
effluents python » fluent python (Expandir a busca), effluents with (Expandir a busca), effluents on (Expandir a busca)
using effluents » using effluent (Expandir a busca), sink effluents (Expandir a busca), washing effluents (Expandir a busca)
code decrease » oxide decrease (Expandir a busca), roads decrease (Expandir a busca), to decrease (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)

Você pode obter mais resultados ajustando o argumento de busca.

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