对于下面的代码，我有一个Map和一个“cookie”的例子，它包含了我想通过python添加到SQLAchalemy的一些信息。正如你所看到的，一些字段，如Farmloc、TreasureMap和Crafts都有多个条目。我搜索了一下，除了Enum之外没有找到其他的条目。但是这给我带来了一些麻烦。有没有比我在这里所做的更好的方法呢？使用Python3.6.1和SQLAchalemy 1.1.11

import csv, sqlalchemy
from sqlalchemy import Column, String, Integer, ForeignKey, Numeric, Boolean
from sqlalchemy.ext.declarative import declarative_base
import sqlite3
from enum import Enum, auto
import enum
from sqlalchemy import create_engine

engine = create_engine('sqlite:///:memory:', echo=True) #TEST DB
    
Base = declarative_base()

class Crystal(Base):
    __tablename__ = 'crystals'
    dbID = Column(Integer, primary_key=True)
    ItemName = Column(String, index=True, nullable=False) #Full name, (ie. Earth Shard, Wind Crystal, Fire Cluster)
    ItemType = Column(String) #Fire, Earth, Wind, Ice, Water ONLY
    ItemPow = Column(String) #Shard, Crystal, Cluster ONLY
    Farmloc = Column(String) #Where player can farm
    Retainer = Column(Boolean) #If retainer can farm
    RetainerQ = Column(Integer) #Quantity retainer gets
    Levee = Column(Boolean) #Any Levees rewards these.
    TreasureMap = Column(String) #False=NO, otherwise Types listed
    Desynthed = Column(String) #False=NO, otherwise Herb1, Herb2, Ore1, etc
    Crafts = Column(String) #Crafts associated with (ie Earth w LWR)
    Price = Column(Integer) #MB price (Should be used as ref for all craftables)

Session = sessionmaker(bind=engine)
session = Session()
    
cc_cookie = Crystal(dbID = 1,

                        Price = 500)       

Base.metadata.create_all(engine)

session.add(cc_cookie)
session.commit()
