Talvez deva tentar algumas variações de ortografia:
extracting methods » extraction methods (Expandir a busca), extractive methods (Expandir a busca), extraction method (Expandir a busca)
coder functions » power functions (Expandir a busca), order functions (Expandir a busca), colour functions (Expandir a busca)
and extracting » and extraction (Expandir a busca), and extractive (Expandir a busca), on extracting (Expandir a busca)
functions and » function and (Expandir a busca), functional and (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
using codigo » using indigo (Expandir a busca), using coding (Expandir a busca), using codium (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder functions and extracting methods ) OR ( using codigo python python programming ))~.
