Perhaps you should try some spelling variations:
"and computational python computer program" » "and computacional python computer program" (Expand search), "and computacional vpython computer program" (Expand search), "and computacionais python computer program" (Expand search), "_ computational python computer program" (Expand search)
"based computation and computational program" » "based computation _ computational program" (Expand search), "based computational and computational program" (Expand search), "based competition and computational program" (Expand search), "based compilation and computational program" (Expand search), "based computation of computational 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: (("and computational python computer program") OR ("based computation and computational program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational python computer program\") OR (\"based computation and computational program\"))".
• Removing quotes may allow a broader search: (( and computational python computer program ) OR ( based computation and computational program )).
• Adding a wildcard symbol may retrieve word variants: (("and computational python computer program") OR ("based computation and computational program"))*.
