Perhaps you should try some spelling variations:
"and computation and basic problems" » "and computational and basic problems" (Expand search), "of computation and basic problems" (Expand search), "and computation of basic problems" (Expand search), "and computation and basis problem" (Expand search), "and computation and plastic problems" (Expand search), "and computation and dynamic problems" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python python python programming" (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: "((\"and computation and basic problems\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation and basic problems ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation and basic problems") OR ("using python python python programming"))*.
