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