Flask Basics - Cookies - 500 Internal Server Error

Hello everyone! I'm trying to use to Flask Basics course on my own webpage. Trying to get the form to save input information from a cookie exactly like how it's done in the course. However, I'm getting a 500 internal server error. Console is giving the following output.

app.py", line 8, in get_saved_data
    data = json.loads(request.cookies.get('character'))
NameError: global name 'request' is not defined

Here is my code:

import json
from flask import Flask, render_template, redirect, url_for, make_response

app = Flask(__name__)

def get_saved_data():
    try:
        data = json.loads(request.cookies.get('character'))
    except TypeError:
        data = {}
    return data

@app.route('/')
def index():
    data = get_saved_data()
    return render_template('index.html', saves=data)

@app.route('/email', methods=['POST'])
def email():
    response = make_response(redirect(url_for('index')))
    data = get_saved_data()
    data.update(dict(request.form.items()))
    response.set_cookie('character', json.dumps(data))
    return response

<form action="{{ url_for('email') }}" method=POST class="form_class">
<div class="row">
<div class="mew_form clearfix">
  <div class="col-sm-12" id="result"></div>

<div class="col-sm-6">

<input value="{{ saves.get('name', 'Name')}}" placeholder="Your Name" class="form_inputs" id="name" name="name" required="required">

</div>
<div class="col-sm-6">

<input value="{{ saves.get('email', 'Email')}}" placeholder="Your Email" class="form_inputs" id="email" name="email" required="required">

</div>

 <div class="col-sm-12">

 <textarea value="{{ saves.get('message', 'Message')}}" placeholder="Your Message" class="form_inputs form_textarea" id="message" name="message" required="required"></textarea>

</div>

 <div class="col-xs-12">

<div class="button_div  center_on_mobile">
<input id="submit_handle" type="submit" style="display: none" />
<a href="#" id="submit_btn" class="bg_pink button button_default_style open_sans bg_before_navy"> <i class="fa fa-envelope" aria-hidden="true"></i> Send Message</a>

</div>

</div>

</div>

</div>

    </form>

it seems like you forgot to import request.

from flask import request
