Talvez deva tentar algumas variações de ortografia:
based estimates » based estimation (Expandir a busca), and estimates (Expandir a busca)
on programming » in programming (Expandir a busca), cone programming (Expandir a busca), and programming (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)
coding python » codigo python (Expandir a busca), codigos python (Expandir a busca), using python (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)

estimates on » estimates of (Expandir a busca), estimates in (Expandir a busca), estimates and (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder python coding python ) OR ( python based estimates on programming ))~.
