Perhaps you should try some spelling variations:
"based computation and visual programming" » "based computation and fetal programming" (Expand search), "based computational and visual programming" (Expand search), "based competition and visual programming" (Expand search), "based compilation and visual programming" (Expand search), "based computation of visual programming" (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: "((\"based computation and visual programming\") OR (\"using python python python programming\"))~".
• Removing quotes may allow a broader search: (( based computation and visual programming ) OR ( using python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based computation and visual programming") OR ("using python python python programming"))*.
