I spent a lot of time searching for a solution to this problem and finally created something like this:

from sqlalchemy import inspect

with open(file_to_write, 'w') as file:
    out_csv = csv.writer(file, lineterminator='\n')

    columns = [column.name for column in inspect(Movies).columns][1:]
    out_csv.writerow(columns)

    session_3 = session_maker()

    extract_query = [getattr(Movies, col) for col in columns]
    for mov in session_3.query(*extract_query):
        out_csv.writerow(mov)

    session_3.close()

It creates a CSV file with column names and a dump of the entire "movies" table without "id" primary column.
