sqlalchemy close all connection

I'm trying to drop my database using sqlalchemy:

def dropDb(self, dbName):
    self.closeConnection()
    self.selectDb(None)
    self.execute("drop database %s" % dbName)

def closeConnection(self):
    self._Session.close_all()
    self._engine.dispose()
    del self._Session
    del self._engine

I create the engine with:

sqlalchemy.create_engine(connection_string, poolclass = NullPool)

But I am getting the following error:

Detail ProgrammingError: (ProgrammingError) ('42000', '[42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot drop database "test_db" because it is currently in use. (3702) (SQLExecDirectW)') 'drop database test_db' ()

How can I forcibly close ALL connections?

The current method for closing all connections using the SQLAlchemy sessions api is

from sqlalchemy.orm import close_all_sessions

close_all_sessions()

as session.close_all() is deprecated.
