I am working through the quickstart guide and testing out templates, and this code snippet confused me a bit:

from flask import render_template

@app.route('/hello/')
@app.route('/hello/<name>')
def hello(name=None):
    return render_template('hello.html', name=name)

I wasn't sure why name=name was necessary. I learned that the first name is referring to the variable in the referenced html file:

<!doctype html>
<title>Hello from Flask</title>
{% if name %}
  <h1>Hello {{ name }}!</h1>
{% else %}
  <h1>Hello, World!</h1>
{% endif %}

This may be trivial, but since it confused me, I thought it might of confused others. I wanted to suggest something like this:

@app.route("/hello/")
@app.route('/hello/<name>')
def hello(name=None):
    return render_template('hello.html', person=name)

with the html file looking like this:

<!doctype html>
<title>Hello from Flask</title>
{% if person %}
  <h1>Hello {{ person }}!</h1>
{% else %}
  <h1>Hello, World!</h1>
{% endif %}

I think this helps differentiate the variable in the html file from the url variable. Let me know your thoughts. 😄

Yes, just wanted to bring it up here first because the contribution guidelines said to. I'll go ahead and do that!
