Talvez deva tentar algumas variações de ortografia:
role complexity » code complexity (Expandir a busca), rate complexity (Expandir a busca), tone complexity (Expandir a busca)
testing python » teaching python (Expandir a busca), testing method (Expandir a busca), using python (Expandir a busca)
using testing » using resting (Expandir a busca), using nesting (Expandir a busca), ring testing (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 role complexity control program ) OR ( using testing python python programming ))~.
