如何在sqlalchemy for mysql中添加一列后的另一列？

from sqlalchemy import create_engine, MetaData, Table, Column, Integer

engine = create_engine('mysql://username:password@host:port/database')
metadata = MetaData(bind=engine)
table = Table('your_table', metadata, autoload=True)

new_column = Column('new_column', Integer)
new_column.create(table)

from sqlalchemy import text

alter_statement = text('ALTER TABLE your_table ADD COLUMN another_column INTEGER')
engine.execute(alter_statement)
