Talvez deva tentar algumas variações de ortografia:
placement program » placement problem (Expandir a busca), payment program (Expandir a busca), enhancement program (Expandir a busca)
using placement » using replacement (Expandir a busca), sling placement (Expandir a busca), using platelet (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (Expandir a busca)
coder using » coders using (Expandir a busca), cover using (Expandir a busca), code using (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 coder using placement program ) OR ( in python python python programming ))~.
