Talvez deva tentar algumas variações de ortografia:
propagation pythons » propagation methods (Expandir a busca), propagation method (Expandir a busca), propagation path (Expandir a busca)
python propagation » photon propagation (Expandir a busca), method propagation (Expandir a busca), yacon propagation (Expandir a busca)
oo programming » to programming (Expandir a busca), logo programming (Expandir a busca), _ programming (Expandir a busca)
pythons python » python python (Expandir a busca), pitons python (Expandir a busca), piton python (Expandir a busca)
code python » codigo python (Expandir a busca), pacote python (Expandir a busca)
code code » code cdc (Expandir a busca)
python oo » python of (Expandir a busca), python to (Expandir a busca), python _ (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code python oo programming ) OR ( python propagation pythons python programming ))~.
