Talvez deva tentar algumas variações de ortografia:
commitment contracts » investment contracts (Expandir a busca), treatment contracts (Expandir a busca), commitment atraves (Expandir a busca)
contracts program » contract program (Expandir a busca), contratos programa (Expandir a busca), contrato programa (Expandir a busca)
coding python » codigo python (Expandir a busca), codigos python (Expandir a busca), using python (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
using coding » using coping (Expandir a busca), using coating (Expandir a busca), using cooking (Expandir a busca)
model and » modeling and (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( model and commitment contracts program ) OR ( using coding python python programming ))~.
