通过sqlalchemy操作mysql

# 安装 pip3 install sqlalchemy

import sqlalchemy

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

# 创建连接
engine = create_engine("mysql+pymysql://root:abc123@localhost/testdb",encoding="utf-8",echo=True)

# 生成ORM基类
Base = declarative_base()

class User(Base):
    __tablename__ = 'user'
    id = Column(INTEGER,primary_key=True)
    name = Column(String(32))
    password = Column(String(64))

Base.metadata.create_all(engine)  # 创建表结构

Session_class = sessionmaker(bind=engine)  # 创建与数据库连接会话的类
Session = Session_class()  # 生成session实例    #cursor

user_obj = User(name="dennis",password="abc123")    #生成要创建的数据对象
user_obj2 = User(name="alex",password="abcd")
print(user_obj.name,user_obj.id)
Session.add(user_obj)
Session.add(user_obj2)

Session.commit()
