How to connect MySQL database using Python (mysql.connector) remotely?

What I want to implement is a Python script that performs operations on a database.

The database is hosted on a PC A [it is my personal PC (OS = Windows 10), on which I have installed XAMMP to manage a db (’‘MySQL’’)].
Through phpMyAdmin I created 2 types of user:

  1. Root “type” user: with this user I can only access from the PC on which the DB is present (from “localhost”);
  2. Generic “type” user: with this user I want to access the DB on PC A, through the Python script, from any host (in alternative, from a specific remote host different from “localhost”).

The problem is that I cannot connect from a remote host (different from “localhost”) to the database hosted on PC A by the “generic” user via the Python script.

I forwed port “3306” on the firewall and modify the configuration file “my.ini” as follows (specifically I entered bind-address = 0.0.0.0), but without success:

Example MySQL config file for small systems.

#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# C:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.


# The following options will be passed to all MySQL clients
[client]
# password       = your_password
port=3306
socket="C:/xampp/mysql/mysql.sock"




# Here follows entries for some specific programs

# Change here for bind listening

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
# log-bin deactivated by default since XAMPP 1.4.11
#log-bin=mysql-bin


# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id   =1


# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended
#log-bin=mysql-bin

Below the Python code to establish the connection with the DB:

import mysql.connector as mysql
import socket

hostname = socket.gethostname()
IP_address = socket.gethostbyname(hostname)


user=input("User: ")
password=input("Password: ")


db=mysql.connect(
    host=IP_address,
    user=user,
    port=3306,
    password=password,
    database="Example_db")


print("connected to: ",db.get_server_info())

If I use the user “root” from the “localhost” I can connect to the DB otherwise the connection fails (E.g. From a remote host different from localhost, Connected to the same Home LAN network).

What can I do to connect “remotely”?
