Talvez deva tentar algumas variações de ortografia:
functions improvements » functional improvements (Expandir a busca), function improvement (Expandir a busca), functional improvement (Expandir a busca)
coder function » modern function (Expandir a busca), power function (Expandir a busca), over function (Expandir a busca)
java functions » gamma functions (Expandir a busca), and functions (Expandir a busca), zeta functions (Expandir a busca)
function java » function j (Expandir a busca), function job (Expandir a busca), function jump (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (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 function java functions improvements ) OR ( using in python python programming ))~.
