I used mysql.connector python library to make changes to my local SQL server databases using:

from __future__ import print_function
import mysql.connector as kkcnx = kk.connect(user='root', password='password123',host='localhost',database='db')
cursor = cnx.cursor(buffered=True)
sql = "DELETE FROM examples WHERE id = 4"
number_of_rows = cursor.execute(sql)
cnx.commit()   
cnx.close()

This works fine, but when i try the same code with a change only to the 'host' parameter, with something like,

host='xxx.xxx.xxx.xxx'

(where the IP is that of a server connected to my local network.), it won't update that particular data base in that server.

The error thrown is something like:

mysql.connector.errors.DatabaseError: 2003 (HY000): Can't connect to MySQL server on 'xx.xxx.x.xx' (10060)

Why wouldn't this work?

First, you must check if your local IP can acces to your remote server (check if you are an IP restriction on your server), after check if your mysql database use the default port or not, If not you must precise the port in your code.
