this is the code in python

from flask import Flask, render_template, request
from flask_bootstrap import Bootstrap
from flaskext.mysql import MySQL
from flask_admin import Admin
from flask_admin.contrib.sqla import ModelView
import MySQLdb



app = Flask(__name__)
mysql = MySQL()

# MySQL configurations
app.config['MYSQL_DATABASE_USER'] = 'root'
app.config['MYSQL_DATABASE_PASSWORD'] = ''
app.config['MYSQL_DATABASE_DB'] = 'movedb'
app.config['MYSQL_DATABASE_HOST'] = 'localhost'
mysql.init_app(app)
Bootstrap(app)
conn = mysql.connect()

    @app.route('/consultamovil.html', methods=["GET","POST"])
def consultamovil():
    db = mysql.connect(host="localhost",user="root",passwd="",db="movedb")


    cursor = db.cursor()
    varpatente= request.form["patente"]
    varinterno= request.form["interno"]
    varmarca= request.form["marca"]
    vararea= request.form["area"]

    query = "SELECT  moviles.Marca,  moviles.Interno, areas.Area_Responsable FROM moviles, areas where moviles.Id_Area=areas.Id_Area and moviles.Patente= '%s' " % varpatente
    cursor.execute(query)
    var = cursor.fetchone()
    if var != None:
        for (Marca, Interno, Area_Responsable) in cursor:
             varmarca= Marca
             varinterno = Interno
             vararea= Area_Responsable
             return render_template('consultamovil.html', marca=varmarca, interno=varinterno, area=vararea)
