Perhaps you should try some spelling variations:
"device application in python programming" » "device applications in python programming" (Expand search), "silicate application in python programming" (Expand search), "device application _ python programming" (Expand search)
"and convolution and using program" » "and coevolution and using program" (Expand search), "and convolutional and using program" (Expand search), "and involution and using program" (Expand search), "and evolution and using program" (Expand search), "and revolution and using program" (Expand search), "and convention and using program" (Expand search), "and convolution and housing program" (Expand search), "and convolution and nursing program" (Expand search), "and convolution and aging 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 convolution and using program") OR ("device application in python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and convolution and using program\") OR (\"device application in python programming\"))".
• Removing quotes may allow a broader search: (( and convolution and using program ) OR ( device application in python programming )).
• Adding a wildcard symbol may retrieve word variants: (("and convolution and using program") OR ("device application in python programming"))*.
