Oracle (MySQL)现在支持纯Python连接器。这意味着不需要安装二进制文件:它只是一个Python库。它叫做“连接器/Python”。

http://dev.mysql.com/downloads/connector/python/

安装完成后，您可以在这里看到一些使用示例

这是Mysql数据库连接

from flask import Flask, render_template, request
from flask_mysqldb import MySQL

app = Flask(__name__)


app.config['MYSQL_HOST'] = 'localhost'
app.config['MYSQL_USER'] = 'root'
app.config['MYSQL_PASSWORD'] = 'root'
app.config['MYSQL_DB'] = 'MyDB'

mysql = MySQL(app)


@app.route('/', methods=['GET', 'POST']) 
def index():
    if request.method == "POST":
        details = request.form
        cur = mysql.connection.cursor()
        cur.execute ("_Your query_")
        mysql.connection.commit()
        cur.close()
        return 'success'
    return render_template('index.html')


if __name__ == '__main__':
    app.run()

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())

参见https://github.com/PyMySQL/mysqlclient-python

在终端上执行以下命令安装mysql connector:

pip install mysql-connector-python

在你的python编辑器中运行这个来连接MySQL:

import mysql.connector

mydb = mysql.connector.connect(
      host="localhost",
      user="username",
      passwd="password",
      database="database_name"
)

执行MySQL命令的示例(在python编辑器中):

mycursor = mydb.cursor()
mycursor.execute("CREATE TABLE customers (name VARCHAR(255), address VARCHAR(255))")    
mycursor.execute("SHOW TABLES")

mycursor.execute("INSERT INTO customers (name, address) VALUES ('John', 'Highway 21')")    
mydb.commit() # Use this command after insert, update, delete commands

只是对上面的回答做了修改。 简单地运行这个命令来安装mysql for python

sudo yum install MySQL-python
sudo apt-get install MySQL-python

记住!区分大小写。

首先，从https://dev.mysql.com/downloads/connector/python/安装python-mysql连接器

在Python控制台输入:

pip install mysql-connector-python-rf
import mysql.connector
