Python equivalent of PHP mysql_fetch_array

I would like to fetch an array in MySQL. Can someone please tell me how to use Python using MySQLdb to do so?

For example, this is what I would like to do in Python:

<?php

  require_once('Config.php'); 

  $q = mysql_query("SELECT * FROM users WHERE firstname = 'namehere'");
  $data = mysql_fetch_array($q);
  echo $data['lastname'];

?>

Thanks.

You can use this (dictionary=True):

import mysql.connector

db = mysql.connector.connect(user='root', password='',host='127.0.0.1', database='test1')

cursor = db.cursor(dictionary=True)
cursor.execute("SELECT * FROM table")

for row in cursor:
    print(row['column'])

In python you have dictionary=True, I have tested in python3. This returns directory which is much similar to associative array in php. eg.

import mysql.connector
cnx = mysql.connector.connect(user='root', password='',host='127.0.0.1',database='test1')
cursor = cnx.cursor(dictionary=True)
sql= ("SELECT * FROM `users` WHERE id>0")
cursor.execute(sql)
results = cursor.fetchall()
print(results)

Try:

import MySQLdb
connection = MySQLdb.connect(host="localhost",  # your host
                     user="root",  # username
                     passwd="password",  # password
                     db="frateData")  # name of the database)
cursor = connection.cursor(MySQLdb.cursors.DictCursor)
cursor.execute('SELECT * FROM users WHERE firstname = %s',['namehere'])
data = cursor.fetchall()
print data['lastname']

Please note that by initiating your cursor by passing the following parameter: "MySQLdb.cursors.DictCursor" a list instead of an array is returned so you can reference the data with their key name, which in your case in lastname.

I would use SQLAlchemy. Something like this would do the trick: 

engine = create_engine('mysql://username:password@host:port/database')
connection = engine.connect()
result = connection.execute("select username from users")
for row in result:
    print "username:", row['username']
connection.close()

  1. Install MySQLdb (the drivers for MySQL for Python). Type pip install mysql-python
  2. Read up on the Python DB API, which is the standard way to access databases in Python.

Then, try this:

>>> import MySQLdb
>>> connection = MySQLdb.connect(database='test')
>>> cursor = connection.cursor()
>>> cursor.execute('SELECT * FROM users WHERE firstname = %s',('somename',))
>>> results = cursor.fetchall()
>>> for i in results:
       print i
