I'm trying to apply the following code to extract features that contain these letters 'MW' within the field called 'CODE' for multiple layers. But I'm getting a SyntaxError for line 5 (defintion query).

import arcpy  
mxd = arcpy.mapping.MapDocument("Current")  
layers = arcpy.mapping.ListLayers(mxd)  
for layer in layers:  
    if layer.supports(definitionQuery)  
         layer.definitionQuery = ""CODE" LIKE "('%MW%')"

  • Could you please edit your question to include the formatted syntax error?

  • Are you trying to extract the features, or update the map?

  • Try removing the parentheses. e.g. """CODE LIKE '%MW%'""". You may also have to add quotes around CODE depending on the field and data type. I'm not sure if arcpy.AddFieldDelimiters works on layers.

You need a colon after your line:

if layer.supports(definitionQuery)

should be:

if layer.supports(definitionQuery):

You should also consider modifying your query as was commented by @smiller. It will make your code easier to read.

  • Thanks, both the colon and the parentheses of my definition query solved the problem!
