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