Talvez deva tentar algumas variações de ortografia:
control problems » control program (Expandir a busca)
decease control » desease control (Expandir a busca), disease control (Expandir a busca), release control (Expandir a busca)
methods python » methods action (Expandir a busca), pythons python (Expandir a busca), methods method (Expandir a busca)
code methods » ode methods (Expandir a busca), cone methods (Expandir a busca), care methods (Expandir a busca)
python code » python coding (Expandir a busca), python redes (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code decease control problems ) OR ( python code methods python programming ))~.
