When I am using SQLALchemy how would one iterate through column names?

Eg.

Column Name 1, Column Name 2, Column Name 3, etc...

The second question is I have the following query: 

root = dbsession.query(MyTable).filter(MyTable.name==u'john').all()

However, when I do:

for row in root:
    print row

I don't get any results. Instead I have to do:

print row.name, row.age, etc...

Can't I just do print row to return data from all the columns?

python sqlalchemy iteration
