Mysqlclient是最好的，因为其他的只支持特定版本的python

 pip install mysqlclient

示例代码

    import mysql.connector
    import _mysql
    db=_mysql.connect("127.0.0.1","root","umer","sys")
    #db=_mysql.connect(host,user,password,db)
    # Example of how to insert new values:
    db.query("""INSERT INTO table1 VALUES ('01', 'myname')""")
    db.store_result()
    db.query("SELECT * FROM new1.table1 ;") 
    #new1 is scheme table1 is table mysql 
    res= db.store_result()
    for i in range(res.num_rows()):
        print(result.fetch_row())

首先安装驱动程序(Ubuntu)

Sudo apt-get install python-pip sudo pip install -U pip Sudo apt-get install python-dev libmysqlclient-dev sudo apt-get install MySQL-python

MySQL数据库连接代码

import MySQLdb
conn = MySQLdb.connect (host = "localhost",user = "root",passwd = "pass",db = "dbname")
cursor = conn.cursor ()
cursor.execute ("SELECT VERSION()")
row = cursor.fetchone ()
print "server version:", row[0]
cursor.close ()
conn.close ()

    import mysql.connector
    import _mysql
    db=_mysql.connect("127.0.0.1","root","umer","sys")

    # Example of how to insert new values:

    db.store_result()
    db.query("SELECT * FROM new1.table1 ;")

    for i in range(res.num_rows()):

你可以用这种方式连接你的python代码到mysql。

import MySQLdb
db = MySQLdb.connect(host="localhost",
                 user="appuser",
                 passwd="",
                 db="onco")

cursor = db.cursor()

SqlAlchemy

SQLAlchemy是Python SQL工具包和对象关系映射器 为应用程序开发人员提供了SQL的全部功能和灵活性。 SQLAlchemy提供了一个完整的著名企业级套件 持久性模式，为高效和高性能而设计 数据库访问，改编成简单的python域语言。

安装

pip install sqlalchemy

原始查询

from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker, scoped_session

engine = create_engine("mysql://<user_name>:<password>@<host_name>/<db_name>")
session_obj = sessionmaker(bind=engine)
session = scoped_session(session_obj)

# insert into database
session.execute("insert into person values(2, 'random_name')")
session.flush()
session.commit()

蠕虫方式

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

Base = declarative_base()
engine = create_engine("mysql://<user_name>:<password>@<host_name>/<db_name>")
session_obj = sessionmaker(bind=engine)
session = scoped_session(session_obj)

# Bind the engine to the metadata of the Base class so that the
# declaratives can be accessed through a DBSession instance
Base.metadata.bind = engine

class Person(Base):
    __tablename__ = 'person'
    # Here we define columns for the table person
    # Notice that each column is also a normal Python instance attribute.
    id = Column(Integer, primary_key=True)
    name = Column(String(250), nullable=False)

# insert into database
person_obj = Person(id=12, name="name")
session.add(person_obj)
session.flush()
session.commit()

这里有一种方法，使用MySQLdb，它只支持Python 2:

#!/usr/bin/python
import MySQLdb

# Connect
db = MySQLdb.connect(host="localhost",
                     user="appuser",
                     passwd="",
                     db="onco")

cursor = db.cursor()

# Execute SQL select statement
cursor.execute("SELECT * FROM location")

# Commit your changes if writing
# In this case, we are only reading data
# db.commit()

# Get the number of rows in the resultset
numrows = cursor.rowcount

# Get and display one row at a time
for x in range(0, numrows):
    row = cursor.fetchone()
    print row[0], "-->", row[1]

# Close the connection
db.close()
