python - How to insert NULL value in SQLAlchemy?

Question

I've a Table with the following column:

Column('type', String(128))

How do I set this column to NULL when inserting a new row in database?

I tried doing this:

self.type = NULL;

There is no NULL type in Python so I don't know how to do it.

Answer 1

Instead of trying

self.type = NULL

try as Yaroslav Admin suggested

self.type = None

As Python's equivalent for NULL is None.
