Any reason that saves.get was used instead of data.get?

  • the value is saves.get, in app.py index(), data is stored in saves
  • any reason that it was not just left as data? 
{% extends "layout.html" %}
{% block content %}
        <form action="{{url_for("save")}}" method="POST"><!--action, method-->
            <label>Name your bear</label><!--abovinput-->
<!-- the value is saves.get, in app.py index(), data is stored in saves-->
<!-- any reason that it was not just left as data? -->
            <input type="text" name="name" value= "{{saves.get("name", '')}}" autofocus><!--enter-->
            <input type="submit" value="Let's build it!"><!--button-->
        </form>

{% endblock %}

from flask import Flask 
from flask import (render_template, redirect, url_for, request,
                  make_response)

app = Flask(__name__)

def get_saved_data():
  try:
    data = json.loads(request.cookies.get("character"))

  data = get_saved_data()
# here, data is stored as saves.  
# Seems like it could have just been left as data
  return render_template("index.html", saves=data)

def save():
  response = make_response(redirect(url_for("index")))
  data = get_saved_data()

  response.set_cookie("character", json.dumps(data))
  return response

I have the similar question, it would be great to get an answer. Do not understand if saves is a variable or a function?
