# Listing All Points In a Polygon Feature Class Using arcPy [closed]

Based on my understanding in coding, I thought the following code will list all points in every feature in my Building polygon feature class:

``````arcpy.env.workspace=r'D:\test.gdb'
rows=arcpy.da.SearchCursor("Building","Shape@")
for row in rows:
print row
for p in row:
print p
``````

But that displays the following results for each polygon:

``````(<Polygon object at 0x324838f0[0x32483ee0]>,)
<geoprocessing describe geometry object object at 0x32483EE0>
``````

What is missing in my code?

• If you want the point coordinates you could use `arcpy.da.SearchCursor("Building","Shape@XY")`, see also desktop.arcgis.com/en/arcmap/10.3/analyze/python/…

• That will return XY of the centroids, not the vertices

• You need to go one level deeper: for part in row[0]: for p in part: print p. Read more about it resources.arcgis.com/en/help/main/10.2/index.html#//… what you're currently displaying is the polygon object, as it says, which is the geometry (SHAPE@); a polygon is made of parts (at least one RING) and the part is made of points so you need to go polygon->parts->points. Printing p should give you Point object, you might want to print "{},{}".format(p.X,p.Y) to get something sensible to read. That will only do one feature class, you'll need to put in another loop to do all. May 9, 2018 at 5:21
• @BERA, read the question too quick...missed the polygon reference.

Based on @MichaelStimson's comments I solved the problem this way:

``````arcpy.env.workspace=r'D:\hilal\test.gdb'
rows=arcpy.da.SearchCursor("Building","Shape@")
for row in rows:
print row
for p in row[0]:
for r in p:
print r
``````

This display every polygon and it's polygon points.

• Now the next step is to do for FC in arcpy.ListFeatureClasses('*','POLYGON'): with arcpy.da.SearchCursor(FC,'SHAPE@'): for row in rows: to do all the polygon feature classes in your workspace. May 9, 2018 at 6:02
• Greate, I will try this May 9, 2018 at 6:57
• This is the memory address of your polygon object i.e a pointer to polygon <Polygon object at 0x324838f0[0x32483ee0]>. The data you extracted is inside the polygon object May 13, 2018 at 1:36
