Talvez deva tentar algumas variações de ortografia:
formulate problems » formulation problems (Expandir a busca), formular problema (Expandir a busca), formulation problem (Expandir a busca)
coding formulate » coding format (Expandir a busca), coatings formulated (Expandir a busca), erding formula (Expandir a busca)
python coding » action coding (Expandir a busca), python code (Expandir a busca)
coding pitons » loading pistons (Expandir a busca)
coder python » codigo python (Expandir a busca), compra python (Expandir a busca)
using coding » using coping (Expandir a busca), using coating (Expandir a busca), using cooking (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

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