I want to use the Python field calculator to remove the hyphen from a field column. For example, I would like to parse out the hyphen from an entry like "123-45-6789" and read "123456789".
Use the built-in
Make sure Python is checked in the Parser at the top
Put this in the Expression box (replacing "FieldName" with your own):
This will replace any instance of a "-" with an empty string.
