Talvez deva tentar algumas variações de ortografia:
coder extending » or extending (Expandir a busca), modules extending (Expandir a busca), azores extending (Expandir a busca)
r programming » _ programming (Expandir a busca), c programming (Expandir a busca), pair 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)
extending r » extending _ (Expandir a busca), extending y (Expandir a busca), extending to (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder extending r programming ) OR ( _ python python python programming ))~.
