Talvez deva tentar algumas variações de ortografia:
periodic programming » period programming (Expandir a busca), hiperbolic programming (Expandir a busca), heuristic programming (Expandir a busca)
object periodic » project periodic (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder object » model object (Expandir a busca), copper objects (Expandir a busca), older objects (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder object periodic programming ) OR ( in python python python programming ))~.
