Perhaps you should try some spelling variations:
coder functions » power functions (Expand search), order functions (Expand search), colour functions (Expand search)
case extraction » cane extraction (Expand search), phase extraction (Expand search), based extraction (Expand search)
functions case » functions are (Expand search), functions and (Expand search), functions at (Expand search)
codigos python » codigo python (Expand search)
using codigos » usando codigos (Expand search), using coding (Expand search), using codium (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (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: "(( coder functions case extraction methods ) OR ( using codigos python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder functions case extraction methods ) OR ( using codigos python python programming ))*.
