Perhaps you should try some spelling variations:
"by computation using structure program" » "by computations using structure program" (Expand search), "by computation in structure program" (Expand search), "by composition using structure program" (Expand search), "by computation using structured program" (Expand search), "by computation using structured programs" (Expand search), "by computation using destructive program" (Expand search), "by computation using structural program" (Expand search), "by computation using unstructured program" (Expand search), "by computational using structure program" (Expand search), "of computation using structure program" (Expand search), "_ computation using structure program" (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: "((\"by computation using structure program\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( by computation using structure program ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("by computation using structure program") OR ("using python python python programming"))*.
