Perhaps you should try some spelling variations:
"and computation of complex program" » "and computational of complex program" (Expand search), "of computation of complex program" (Expand search), "and computation of simplex program" (Expand search), "and computation of complex programmes" (Expand search), "and computation of complex prograded" (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.

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