Talvez deva tentar algumas variações de ortografia:
model perceptions » local perceptions (Expandir a busca), social perceptions (Expandir a busca), maternal perceptions (Expandir a busca)
perceptions from » perceptions of (Expandir a busca), perceptions on (Expandir a busca), perceptions about (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)
python model » python module (Expandir a busca), python code (Expandir a busca), python morelia (Expandir a busca)
in python » _ python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder python model perceptions from ) OR ( in python python python programming ))~.
