Well depending on what sql database you are using you can pip install pymssql for microsoft sql (mssql), psycopg2 for postgres (psql) or mysqldb for mysql databases Here are a few examples of using it

Microsoft sql

import pymssql

conn = pymssql.connect(server=server, user=user, password=password, database=db)
cursor = conn.cursor()

cursor.execute("SELECT COUNT(MemberID) as count FROM Members WHERE id = 1")
row = cursor.fetchone()

conn.close()

print(row)

Postgres

import psycopg2

conn = psycopg2.connect(database=db, user=user, password=password, host=host, port="5432")
cursor = conn.cursor()

cursor.execute('SELECT COUNT(MemberID) as count FROM Members WHERE id = 1')
row = cursor.fetchone()

conn.close()

print(row)

mysql

import MySQLdb

conn = MySQLdb.connect(host=host, user=user, passwd=passwd, db=db)
cursor = conn.cursor()

cursor.execute('SELECT COUNT(MemberID) as count FROM Members WHERE id = 1')
row = cursor.fetchone()

conn.close()

print(row)
