Perhaps you should try some spelling variations:
"device applications in python programming" » "medicine applications in python programming" (Expand search), "mobile applications in python programming" (Expand search), "space applications in python programming" (Expand search), "device applications _ python programming" (Expand search)
"and convolutional and clean program" » "and conventional and clean program" (Expand search), "of convolutional and clean program" (Expand search), "_ convolutional and clean program" (Expand search), "and convolution and clean program" (Expand search), "and convolutional codes clean program" (Expand search), "and convolutional and learn program" (Expand search), "and convolutional and loan program" (Expand search), "and convolutional and bean program" (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: (("and convolutional and clean program") OR ("device applications in python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and convolutional and clean program\") OR (\"device applications in python programming\"))".
• Removing quotes may allow a broader search: (( and convolutional and clean program ) OR ( device applications in python programming )).
• Adding a wildcard symbol may retrieve word variants: (("and convolutional and clean program") OR ("device applications in python programming"))*.
