def __repr__(self): return f"Paper(id={self.id}, title='{self.title}', content='{self.content}')"

engine = create_engine('sqlite:///example.db') # For example, a SQLite database Base = declarative_base()

class Paper(Base): __tablename__ = 'papers' id = Column(Integer, primary_key=True) title = Column(String) content = Column(String)

print(f"Paper saved to {filename}")

However, if you're asking for a DDL (Data Definition Language) example in Python, it's more related to database schema definitions.

# Example usage new_paper = Paper(title="My Paper Title", content="This is my paper content.") session.add(new_paper) session.commit()

Base.metadata.create_all(engine)

# Save the document to a file doc.save(filename)
