如何统计字符串数据列[Python]中SQLAlchemy中的数据？

from sqlalchemy import create_engine, func
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base

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

Base = declarative_base()

class YourTable(Base):
    __tablename__ = 'your_table_name'
    id = Column(Integer, primary_key=True)
    string_column = Column(String)

result = session.query(YourTable.string_column, func.count(YourTable.string_column)).group_by(YourTable.string_column).all()

for row in result:
    string_value = row[0]
    count = row[1]
    print(f"字符串'{string_value}'的数据量为{count}")
