Perhaps you should try some spelling variations:
"surface functionality in python programming" » "surface functionalities in python programming" (Expand search), "surface functionalized in python programming" (Expand search), "surface functional in python programming" (Expand search), "surface functionality and python programming" (Expand search), "surface functionality of python programming" (Expand search), "surface functionality _ python programming" (Expand search)
"based convolutional code coding program" » "and convolutional code coding program" (Expand search), "deep convolutional code coding program" (Expand search), "2d convolutional code coding program" (Expand search), "based convolutional codes coding program" (Expand search), "based convolutional and coding program" (Expand search), "based convolucional cnn coding program" (Expand search), "based convolutional code cloning program" (Expand search), "based convolutional code loading program" (Expand search), "based convolutional code cooling programs" (Expand search), "based convolutional code codigo program" (Expand search), "based convolutional code according program" (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: "((\"based convolutional code coding program\") OR (\"surface functionality in python programming\"))~".
• Removing quotes may allow a broader search: (( based convolutional code coding program ) OR ( surface functionality in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("based convolutional code coding program") OR ("surface functionality in python programming"))*.
