Perhaps you should try some spelling variations:
"using computational vpython complex objects" » "using computacional vpython complex objects" (Expand search), "using computacional python complex objects" (Expand search), "using computational method complex objects" (Expand search), "and computational vpython complex objects" (Expand search), "using computational vpython complex projects" (Expand search), "using computational vpython compact objects" (Expand search)
"using coding python python programming" » "using codigo python python programming" (Expand search), "using codigos python python programming" (Expand search), "using using python python programming" (Expand search), "using coding pythons python programming" (Expand search), "using coding piton python programming" (Expand search), "using coding pitons python programming" (Expand search), "using coping python python programming" (Expand search), "using coating python python programming" (Expand search), "using cooking 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: "((\"using computational vpython complex objects\") OR (\"using coding python python programming\"))~".
• Removing quotes may allow a broader search: (( using computational vpython complex objects ) OR ( using coding python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("using computational vpython complex objects") OR ("using coding python python programming"))*.
