Talvez deva tentar algumas variações de ortografia:
tone complexity » the complexity (Expandir a busca), code complexity (Expandir a busca), time complexity (Expandir a busca)
cooling python » cooling method (Expandir a busca), online python (Expandir a busca), modeling vpython (Expandir a busca)
using cooling » using cooking (Expandir a busca), during cooling (Expandir a busca), using coupling (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder » poder (Expandir a busca), codes (Expandir a busca), coded (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder tone complexity control program ) OR ( using cooling python python programming ))~.
