Talvez deva tentar algumas variações de ortografia:
based programming » and programming (Expandir a busca), based program (Expandir a busca), cone programming (Expandir a busca)
fractions python » fractions on (Expandir a busca), fractions math (Expandir a busca)
and fractions » and actions (Expandir a busca), and functions (Expandir a busca), and interactions (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)
python based » action based (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 python based programming ) OR ( python and fractions python programming ))~.
