Store fieldnames in a string variable

Ed_ — Wed, 20 Mar 2024 13:25:56 GMT

Usually one can get the list of field/column names using the following code. Now, I would like to store the field names as strings in a variable. How can I do this?

Desired output:

var = ("Field 1", "Field2", "Field.3")

Another try (does not work either):

for field in fields: var = str(field.name)

Current code:

fields = arcpy.ListFields('df') # Show column names for field in fields: print(field.name)

I've taken what you asked for quite literally (i.e. replaced single speech-marks with doubles and square brackets with curly) hence the multiple replace operations on the final variable but I think it should achieve what you're after

fields = arcpy.ListFields('df') fieldlist = [] for field in fields: fieldlist.append(field.name) var = str(fieldlist).replace("'", '"').replace("[", "(").replace("]", ")") print var

The major issue you are having is that arcpy.ListFields returns just that, fields or field objects, and not field names.

var = [field.name for field in arcpy.ListFields('df')]

Hi Joshua, I might ping you, if you have sometime, since now I am trying to combine the code in your reply with the code you helped with earlier in the split comma separated values post. Thank you!
