Perhaps you should try some spelling variations:
"python code vpython python programming" » "python code python python programming" (Expand search), "python code pythons python programming" (Expand search), "python code piton python programming" (Expand search), "python 3d vpython python programming" (Expand search)
"coding and python arduino programmable" » "coding rna python arduino programmable" (Expand search), "coding in python arduino programmable" (Expand search), "coding on python arduino programmable" (Expand search), "coding api python arduino programmable" (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: "((\"coding and python arduino programmable\") OR (\"python code vpython python programming\"))~".
• Removing quotes may allow a broader search: (( coding and python arduino programmable ) OR ( python code vpython python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coding and python arduino programmable") OR ("python code vpython python programming"))*.
