I'm trying to only return information on a selected feature in a shapefile. According to other answers online, searchcursors should only act on selected features, but for whatever reason it's providing me with all the features in the shapefile.

Here's a basic example of what I'm working with:

for row in arcpy.SearchCursor(shapefile):
    print row.TEXT

This code prints the output from the "TEXT" field for all features, not only the one I have selected.

  • How are you selecting the features? – Aaron Feb 17 '17 at 6:46
  • Can you post your entire code? I can't reproduce the problem using the snippet you've provided (i.e. select features, run your code, returns only selected features). – phloem Feb 17 '17 at 19:34

As an alternative to making a selection, with a SearchCursor you have the option to use the where_clause parameter, which will limit the records returned.

See Building a Query Expression for more information.

Instead of opening the SearchCursor on the whole shapefile you could open it on a layer that has that shapefile as its data source.

Any selections (spatial and/or attribute) on that layer will be respected by the cursor.
