AFAICT, it does not seem possible to create a table with the Python library, as table_constraints is inexplicably unsettable. (You can't, AFAICT, create PK/FK constraints via the Console, either, so I am beginning to wonder how one does make use of this feature.)

Steps to reproduce

1. Attempt to create a table w/ a primary key or FK

Code example

Where a_bq_table is a Table, and constraints is a TableConstraints

In [72]: a_bq_table.table_constraints = constraints
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

----> 1 a_bq_table.table_constraints = constraints
