Talvez deva tentar algumas variações de ortografia:
operator approximation » operator application (Expandir a busca), vector approximation (Expandir a busca), pair approximation (Expandir a busca)
python operator » phone operator (Expandir a busca), method operator (Expandir a busca), perron operator (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (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 python operator approximation ) OR ( in python python python programming ))~.
