Perhaps you should try some spelling variations:
commitment contratos » commitment contracts (Expand search), commitment cooperation (Expand search), commitment generations (Expand search)
contratos programa » contrato programa (Expand search), contract program (Expand search), contratos promessa (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
using script » using scripts (Expand search), during script (Expand search), using scripting (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code AND commitment contratos programa ) OR ( using script python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( code AND commitment contratos programa ) OR ( using script python python programming ))*.
