I am trying to write a Python script that adds several fields to a feature class and then calculates those new fields. This is a process I will have to do to multiple layers so I am hoping to automate this. I am using ArcGIS Pro 2.4.3 and Python 3.7. I have the following script: # Import system modules import arcpy # Set environment settings arcpy . env . workspace = r "D:\Project Data\System Analysis\Jan 2020\Sys_analysis_2020\Sys_analysis_2020.gdb" table = "single_market_area_no_urban_working_intersect" # Add Fields arcpy .

fields = [ [ "total_pop_intersect" , "!total_pop* (!Shape_Area!/!tract_area!)" ] are you missing an ! mark ? "!total_pop! *

are you missing an ! mark ?

As the error message indicates, you have an unexpected indent error . This error occurs when a statement is unnecessarily indented or its indentation does not match the indentation of former statements in the same block. Python not only insists on indentation, it insists on consistent indentation . You are free to choose the number of spaces of indentation to use, but you then need to stick with it. If you indent one line by 4 spaces, but then indent the next by 2 (or 5, or 10, or ...), you'll get this error.

However, by default, mixing tabs and spaces is still allowed in Python 2 , but it is highly recommended not to use this "feature". Python 3 disallows mixing the use of tabs and spaces for indentation. Replacing tabs with 4 spaces is the recommended approach for writing Python code .

Dan_Patterson ,

I feel quite foolish now because after digging into this a little deeper, I realized I was using the alias instead of the field name. Normally, that would not be a problem but because I joined two tables together, it placed the table name in front of the field name. I was able to go in an add the correct field name with the table name in front of it and everything ran fine. Thanks for working on this with me.
