如何去掉SQLAlchemy过滤器参数中的括号？

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

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

# 定义数据模型
Base = declarative_base()

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

# 查询年龄大于等于18且小于等于30的用户
age_filter = literal(User.age >= 18) & literal(User.age <= 30)
users = session.query(User).filter(age_filter).all()

# 打印查询结果
for user in users:
    print(user.name, user.age)
