Talvez deva tentar algumas variações de ortografia:
placement programming » element programming (Expandir a busca), placement program (Expandir a busca), fragment programming (Expandir a busca)
system placement » system replacement (Expandir a busca), systematic placement (Expandir a busca), system management (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
coder system » cover system (Expandir a busca), code system (Expandir a busca), coded systems (Expandir a busca)
coder coder » coder decoder (Expandir a busca), code code (Expandir a busca), decoder codec (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 system placement programming ) OR ( in python python python programming ))~.
