Perhaps you should try some spelling variations:
"and computational in computer program" » "_ computational in computer program" (Expand search), "and computational and computer program" (Expand search), "and computational _ computer program" (Expand search), "and computational 3d computer program" (Expand search)
"using coding on python programming" » "using coping on python programming" (Expand search), "using coating on python programming" (Expand search), "using cooking on python programming" (Expand search), "using coding of python programming" (Expand search), "using coding in python programming" (Expand search), "using coding an python programming" (Expand search), "using coding _ 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 computational in computer program\") OR (\"using coding on python programming\"))~".
• Removing quotes may allow a broader search: (( and computational in computer program ) OR ( using coding on python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational in computer program") OR ("using coding on python programming"))*.
