Can't connect to MySQL server on 'localhost:3306' (10061) During handling of the above exception in python

i wrote a program to check if program can make connection to MySQL server and if cant connect to server print a error message and this is the program that i wrote

import mysql.connector

is_connected = False

def check_connection():
global is_connected
try:
    db = mysql.connector.connect(
        host="localhost",
        user="root",
        passwd=""
    )

    if db.is_connected():
        print("Connected to MySQL database")
        is_connected = True
except:
    print("Unable to connect to MySQL database check if mysql server is running on defaul port which is 3306")
return is_connected

the whole objective here is print a error message when MySQL server is not running so i stop the server and run the file it works fine when in its own file but when it import to another file and call the check_cconnection method its give this error
