How to change attribute from being read-only

Question

I am getting

Error: AttributeError : attribute is read-only (Python.Runtime.PythonException)

trying to override an existing method for the application running IronPython:

self.attribute = True

How to "unlock" the attribute so it could be overwritten with a new value?

I might be read only for a reason. Is it your code that's doing it or someone elses? — Keith, Jan 30 '17 at 00:02

Most likely self.attribute uses a property. This property only has a getter method so it's read only. To make it writable, you'd have to write a setter method that writes to the private value inside the class.

You should consider this carefully, because most likely there is a very good reason this is a read only property. You could cause a lot of unwanted side effects because the original class designer may have never intended the value to be writable.
