Add field alias if field already exists

Is it possible to add/amend field alias if field already exists i.e. not going the AddField_management() route?

has some good info on field properties

This should get you started

fields = arcpy.ListFields("layer")

for f in fields:
    if f.name == "Something you want to change"
        f.aliasName = "New Alias"

Thanks, hadn't realised the listFields 'getter' could also be used as a setter!

Oh I think you might be right, I may have used field mappings before to set them.

OK, thanks 😞
