Hello , I am doing the Cookies Flask Basics Challenge and its telling me when i try to go online that data is not defined but i cant seem to find it in my code! Can anyone help?

import json

from flask import (Flask,render_template, redirect, url_for, request, 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():
  return render_template('index.html', saves=data)

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

Hi Shan

First thing when you post any code try and use the markdown sheet it helps others to read your code more easily.look at my comment in the view index.

import json

from flask import (Flask,render_template, redirect, url_for, request, 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() # call the function and assign it to data
        return render_template('index.html', saves=data) 


@app.route('/save', methods=['POST'])
def save():
    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

app.run(debug=True, host='0.0.0.0', port=8000)
