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