Perhaps you should try some spelling variations:
"coder functions by computational program" » "coder functions _ computational program" (Expand search), "coder functions and computational program" (Expand search), "power functions by computational program" (Expand search), "order functions by computational program" (Expand search), "colour functions by computational program" (Expand search)
"on python python python programming" » "on pythons python python programming" (Expand search), "on piton python python programming" (Expand search), "on pitons python python programming" (Expand search), "in python pythin python programming" (Expand search), "of python pythof python programming" (Expand search), "_ python pyth_ 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: (("coder functions by computational program") OR ("on python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder functions by computational program\") OR (\"on python python python programming\"))*".
• Removing quotes may allow a broader search: (( coder functions by computational program ) OR ( on python python python programming ))*.
