Perhaps you should try some spelling variations:
"using computational python computer program" » "using computacional python computer program" (Expand search), "using computacional vpython computer program" (Expand search), "using computacionais python computer program" (Expand search), "and computational python computer program" (Expand search)
"based computational on example program" » "and computational on example program" (Expand search), "by computational on example program" (Expand search), "based computational one example program" (Expand search), "based computacional on example program" (Expand search), "based computational and example program" (Expand search), "based computational on examples program" (Expand search), "based computational an example program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("using computational python computer program") OR ("based computational on example program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using computational python computer program\") OR (\"based computational on example program\"))".
• Removing quotes may allow a broader search: (( using computational python computer program ) OR ( based computational on example program )).
• Adding a wildcard symbol may retrieve word variants: (("using computational python computer program") OR ("based computational on example program"))*.
