Perhaps you should try some spelling variations:
"based implementation and coding problem" » "and implementation and coding problem" (Expand search), "based implementation of coding problem" (Expand search), "based implementation and coding problems" (Expand search), "based implementation and coping problem" (Expand search), "based implementation and loading problem" (Expand search), "based implementation and cooling problem" (Expand search), "based implementation and cooking problem" (Expand search)
"using python python python programming" » "using pythons python python programming" (Expand search), "using piton python python programming" (Expand search), "using pitons python python programming" (Expand search), "usando python python python programming" (Expand search), "in python python python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("based implementation and coding problem") OR ("using python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based implementation and coding problem\") OR (\"using python python python programming\"))*".
• Removing quotes may allow a broader search: (( based implementation and coding problem ) OR ( using python python python programming ))*.
