Talvez deva tentar algumas variações de ortografia:
improving author » improving actions (Expandir a busca), improving methods (Expandir a busca), improving acute (Expandir a busca)
python program » action program (Expandir a busca)
python codigo » python coding (Expandir a busca), python code (Expandir a busca)
coder python » compra python (Expandir a busca)
author piton » author position (Expandir a busca), author editor (Expandir a busca), author person (Expandir a busca)
piton python » pitons python (Expandir a busca), in python (Expandir a busca), with python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder python codigo python program ) OR ( improving author piton python programming ))~.
