Print fields indexes of featur class

How can you print out the field index and fields name of all the fields in a feature class?

print out something like this,

0 OBJECTID
1 Shape
2 GlobalID
3 field1
4 field2
5 field3
6 field4
7 field5
etc...

import arcpy #arcpy map read current project # can also pass the full path aprx = arcpy.mp.ArcGISProject("CURRENT") # List of FeatureClasses in Geodatabase featureclasses = arcpy.ListFeatureClasses() # the feature class that you want to check featureclass_name = 'featureclass of interest' # list of field (column) objects in the Attribute Table of the Feature Class fields_ls = arcpy.ListFields(featureclass_name) # object fields_names_ls= [f.name for f in fields_ls] # name for c,i in enumerate(fields_names_ls): print(f'{c:02}-{i}') # zero padded the index to match visually

This was a general example using Python. I zero padded the index to match them visually in case of having more than 10 fields.

you can replace the last line by the following if that is not what you want:

print(f'{c} {i}')

List of feature classes was included just in case you need that, otherwise you can skip that line.

I'm not sure if you're talking about an automated way to do this, but for a quick solution, I usually just right-click the layer / Data Design / Fields. Then click the upper left of that table (with the small triangle) to select everything, then right-click again to copy, then just paste it into Excel. You'll have to add your own "field index" - I don't know of any view in ArcGIS that gives a field "index"

In a python window you could do something this:

i=0 for f in arcpy.ListFields(feature_class): print(str(i) + " " + f.name) i+=1
