Long Interger value to resemble a integer separated by commas

KaraO_Neill — Wed, 04 Jan 2012 17:23:55 GMT

I have been successful at creating a very basic script when ran to populate labels inside of my layout view in ArcMap. I am no python master and have pieced this together from research. I also have to do this about 40 or so labels so if anyone as a way to write this easier, I am all ears/eyes!

************
import arcpy
from arcpy import env
import string

# Set the workspace

mxd = arcpy.mapping.MapDocument("CURRENT")

# Set the variable for each element

epz_n = arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT", "epz_n")[0]
cur2_n = arcpy.SearchCursor("tbl_10_to_EPZ", "[Compass] = 'N'")
epz_wnw = arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT", "epz_wnw")[0]
cur2_wnw = arcpy.SearchCursor("tbl_10_to_EPZ", "[Compass] = 'WNW'")

for row in cur2_n:
    epz_n.text = row.getValue("POP_RATIO")

for row in cur2_wnw:
    epz_wnw.text = row.getValue("POP_RATIO")

mxd.save()
del mxd

*****************

My question is how do I get that value to resemble a integer separated by commas?

If my value is 15000 I want it to look like 15,000.

Thanks for any suggestions.

Google search on
Python format number with commas

yields several options, eg.

Thanks Dan. I will give this a shot...

Although I am not entirely sure where to insert this code or modify it to make it work for me. Do you have a suggestion?

This seems to work. Is there an easier way to do this I have a TON of labels that I need to dynamically populate based on the table values? I have too many constraints in order to use a label engine over multiple projects and make them all look the same way. We are trying to automate this process. Thanks!
