Perhaps you should try some spelling variations:
"coder functions in coverage of" » "power functions in coverage of" (Expand search), "order functions in coverage of" (Expand search), "colour functions in coverage of" (Expand search), "coder functions and coverage of" (Expand search)
"in python python python programming" » "in pythons python python programming" (Expand search), "in piton python python programming" (Expand search), "in pitons python python programming" (Expand search), "_ python python 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: "((\"coder functions in coverage of\") OR (\"in python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder functions in coverage of ) OR ( in python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder functions in coverage of") OR ("in python python python programming"))*.
