Perhaps you should try some spelling variations:
"and computation in visual programming" » "and computation in fetal programming" (Expand search), "and computational in visual programming" (Expand search), "of computation in visual programming" (Expand search), "and computation and visual programming" (Expand search), "and computation of visual programming" (Expand search), "and imputation in visual programming" (Expand search), "and computation in virtual programming" (Expand search)
"using using python python programming" » "using using pythons python programming" (Expand search), "using using piton python programming" (Expand search), "using using pitons python programming" (Expand search), "using usando python python programming" (Expand search), "using in python python programming" (Expand search), "using fusing python python programming" (Expand search), "housing using python python programming" (Expand search), "nursing using 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 in visual programming\") OR (\"using using python python programming\"))~".
• Removing quotes may allow a broader search: (( and computation in visual programming ) OR ( using using python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computation in visual programming") OR ("using using python python programming"))*.
