Migrating to Mysql from SQlite

[atari400]

First, I would like to thank Buran for his support.

Secondly, attached is the working code for anyone whom is interested. I have removed "create user" option for simplicity.

#imports
#don't forget to dos>pip install mysql-connector-python
from tkinter import *
from tkinter import messagebox as ms
import mysql.connector as mysql
 
mydb = mysql.connect(
    host="localhost",
    user="goktan",
    passwd="nopassword64",
    database="testdb"
)
#main Class
class main:
    def __init__(self,master):
        # Window 
        self.master = master
        # Some Usefull variables
        self.username = StringVar()
        self.password = StringVar()
        self.n_username = StringVar()
        self.n_password = StringVar()
        #Create Widgets
        self.widgets()
 
    #Login Function
    def login(self):
        #Establish Connection
        cursor = mydb.cursor()
        #Find user If there is any take proper action
        find_user = ("SELECT * FROM user WHERE username = %s and password = %s")
        cursor.execute(find_user, [(self.username.get()), (self.password.get())])
        result = cursor.fetchall()
        if result:
            self.logf.pack_forget()
            self.head['text'] = self.username.get() + '\n Loged In'
            self.head['pady'] = 150
        else:
            ms.showerror('Oops!','Username Not Found.')
                
        #Frame Packing Methords
    def log(self):
        self.username.set('')
        self.password.set('')
        self.crf.pack_forget()
        self.head['text'] = 'LOGIN'
        self.logf.pack()
         
    #Draw Widgets
    def widgets(self):
        self.head = Label(self.master,text = 'LOGIN',font = ('',35),pady = 10)
        self.head.pack()
        self.logf = Frame(self.master,padx =10,pady = 10)
        Label(self.logf,text = 'Username: ',font = ('',20),pady=5,padx=5).grid(sticky = W)
        Entry(self.logf,textvariable = self.username,bd = 5,font = ('',15)).grid(row=0,column=1)
        Label(self.logf,text = 'Password: ',font = ('',20),pady=5,padx=5).grid(sticky = W)
        Entry(self.logf,textvariable = self.password,bd = 5,font = ('',15),show = '*').grid(row=1,column=1)
        Button(self.logf,text = ' Login ',bd = 3 ,font = ('',15),padx=5,pady=5,command=self.login).grid()
        self.logf.pack()
  
#create window and application object
root = Tk()
root.title("Login Form")
main(root)
root.mainloop()
