Perhaps you should try some spelling variations:
"based instruction python python programming" » "based instruction method python programming" (Expand search), "based instruction on python programming" (Expand search), "based instruction to python programming" (Expand search), "assisted instruction python python programming" (Expand search), "based instruction pythons python programming" (Expand search), "based instruction piton python programming" (Expand search), "based instruction pitons python programming" (Expand search)
"coder functions in robots programming" » "power functions in robots programming" (Expand search), "order functions in robots programming" (Expand search), "colour functions in robots programming" (Expand search), "coder functions in roots programming" (Expand search), "coder functions in robot programming" (Expand search), "coder functions in robotics 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: "((\"coder functions in robots programming\") OR (\"based instruction python python programming\"))~".
• Removing quotes may allow a broader search: (( coder functions in robots programming ) OR ( based instruction python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder functions in robots programming") OR ("based instruction python python programming"))*.
