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 cleaning program" » "and conventional and cleaning program" (Expand search), "of convolutional and cleaning program" (Expand search), "_ convolutional and cleaning program" (Expand search), "and convolution and cleaning program" (Expand search), "and convolutional codes cleaning program" (Expand search), "and convolutional and learning program" (Expand search), "and convolutional and leasing program" (Expand search), "and convolutional and screening program" (Expand search), "and convolutional and clean program" (Expand search), "and convolutional of cleaning 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: "((\"and convolutional and cleaning program\") OR (\"device applications in python programming\"))~".
• Removing quotes may allow a broader search: (( and convolutional and cleaning program ) OR ( device applications in python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and convolutional and cleaning program") OR ("device applications in python programming"))*.
