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。

MySQLdb是最直接的方法。您可以在连接上执行SQL查询。时期。

我更喜欢使用强大的SQLAlchemy，这也是python化的。下面是一个与查询相关的教程，下面是一个关于SQLALchemy的ORM功能的教程。

尝试使用MySQLdb。MySQLdb只支持Python 2。

有一个如何页面在这里:http://www.kitebird.com/articles/pydbapi.html

原文如下:

# server_version.py - retrieve and display database server version

import MySQLdb

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

首先安装驱动程序

pip install MySQL-python   

然后一个基本代码是这样的:

#!/usr/bin/python
import MySQLdb

try:
    db = MySQLdb.connect(host="localhost",      # db server, can be a remote one 
                     db="mydb"                  # database
                     user="mydb",               # username
                     passwd="mydb123",          # password for this username
                     )        

    # Create a Cursor object
    cur = db.cursor()

    # Create a query string. It can contain variables
    query_string = "SELECT * FROM MY_TABLE"

    # Execute the query
    cur.execute(query_string)

    # Get all the rows present the database
    for each_row in cur.fetchall():
        print each_row

    # Close the connection
    db.close()
except Exception, e:
    print 'Error ', e 

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()

参考这里

如果你想避免安装mysql头文件只是为了从python访问mysql，请停止使用MySQLDb。

使用pymysql。它做了MySQLDb做的所有事情，但是它完全是用Python实现的，没有外部依赖。这使得在所有操作系统上的安装过程一致且简单。pymysql是MySQLDb的替代品，在我看来，没有任何理由使用MySQLDb做任何事情…!-在Mac OSX和*Nix系统上安装MySQLDb的PTSD，但这只是我的想法。

安装

安装pymysql

就是这样……你已经准备好了。

来自pymysql Github repo的示例用法

import pymysql.cursors
import pymysql

# Connect to the database
connection = pymysql.connect(host='localhost',
                             user='user',
                             password='passwd',
                             db='db',
                             charset='utf8mb4',
                             cursorclass=pymysql.cursors.DictCursor)

try:
    with connection.cursor() as cursor:
        # Create a new record
        sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
        cursor.execute(sql, ('webmaster@python.org', 'very-secret'))

    # connection is not autocommit by default. So you must commit to save
    # your changes.
    connection.commit()

    with connection.cursor() as cursor:
        # Read a single record
        sql = "SELECT `id`, `password` FROM `users` WHERE `email`=%s"
        cursor.execute(sql, ('webmaster@python.org',))
        result = cursor.fetchone()
        print(result)
finally:
    connection.close()

在现有代码中快速透明地替换MySQLdb

如果你有使用MySQLdb的现有代码，你可以通过以下简单的过程轻松地将其替换为pymysql:

# import MySQLdb << Remove this line and replace with:
import pymysql
pymysql.install_as_MySQLdb()

所有对MySQLdb的后续引用都将透明地使用pymysql。
