Talvez deva tentar algumas variações de ortografia:
coder abstraction » order abstraction (Expandir a busca), model abstraction (Expandir a busca), water abstraction (Expandir a busca)
abstraction by » abstraction _ (Expandir a busca), abstraction of (Expandir a busca), abstraction and (Expandir a busca)
by programming » by reprogramming (Expandir a busca), _ programming (Expandir a busca), c programming (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (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 abstraction by programming ) OR ( _ python python python programming ))~.
