operational failures » operational factors (Expandir a busca), operational measures (Expandir a busca), operational resources (Expandir a busca)
python operational » methods operational (Expandir a busca), on operational (Expandir a busca), non operational (Expandir a busca)
failures problems » failure problems (Expandir a busca), values problems (Expandir a busca), tiles problems (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder python operational failures problems ) OR ( using coding python python programming ))~.
