How to clear a subtype field using python

[SAMIRMOURAD]

Hello,

Is there a function like RemoveDomainFromField but for subtypes ? Or a function that allows us to clear the field of a subtype ? 
Thank you

Do you mean?

or are you looking for the new SUBTYPE@ functionality in cursors?

Let's say that in the exemple below, In Utility Access Type, I would like to remove the link to Domain.
I want to empty the the default value and the domain for AcessType in Utility. I know that I can do it directly on this table, but is there a way of doing it using a pyhton script ?

Thanks

[SAMIRMOURAD]

any suggestions ?
