如何使用sqlalchemy将字典列表中的内容添加到表中？

from sqlalchemy import create_engine, Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker

engine = create_engine('数据库连接字符串')
Session = sessionmaker(bind=engine)
session = Session()

Base = declarative_base()

class MyTable(Base):
    __tablename__ = '表名'
    id = Column(Integer, primary_key=True)
    name = Column(String)
    age = Column(Integer)

Base.metadata.create_all(engine)

data = [
    {'name': '张三', 'age': 20},
    {'name': '李四', 'age': 25},
    {'name': '王五', 'age': 30}
]

for item in data:
    record = MyTable(**item)
    session.add(record)

session.commit()
