Adjust the following Python file so it also collects:

- address

- birthdate (prompt for the user to enter in this format: YYYY-MM-DD)

- Similarly to how it handles name, it should store and get the above variables in the session cookie:

from flask import Flask, render_template, session, redirect, url_for

from flask_wtf import FlaskForm

from wtforms import StringField, SubmitField

from wtforms.validators import DataRequired

from flask_bootstrap import Bootstrap

app = Flask(__name__)

app.config['SECRET_KEY'] = 'hard to guess string'

bootstrap = Bootstrap(app)

class NameForm(FlaskForm):

name = StringField('What is your name?', validators=[DataRequired()])

submit = SubmitField('Submit')

@app.route('/', methods=['GET','POST'])

def index():

form=NameForm()

if form.validate_on_submit():

#we will set up a cookie to store the name

session['name']=form.name.data

#the redirect will help eliminate the refresh warning

return redirect(url_for('index'))

#the following line will get the saved name from the session cookie

return render_template('user5.html', form=form, name=session.get('name'))
