Talvez deva tentar algumas variações de ortografia:
reasoning problems » learning problems (Expandir a busca), nesting problems (Expandir a busca), planning problems (Expandir a busca)
vpython python » python python (Expandir a busca), pythons python (Expandir a busca), piton python (Expandir a busca)
on reasoning » of reasoning (Expandir a busca), in reasoning (Expandir a busca), and reasoning (Expandir a busca)
code vpython » 3d vpython (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
coder on » code on (Expandir a busca), codes on (Expandir a busca), powder on (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder coder on reasoning problems ) OR ( python code vpython python programming ))~.
