Talvez deva tentar algumas variações de ortografia:
coder sampling » under sampling (Expandir a busca), core sampling (Expandir a busca), over sampling (Expandir a busca)
sampling from » sampling error (Expandir a busca), samples from (Expandir a busca), sample from (Expandir a busca)
python coding » python codigo (Expandir a busca), action coding (Expandir a busca), python code (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
from python » from pathogen (Expandir a busca), from anthony (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( coder sampling from python coding ) OR ( _ python python python programming ))~.
