Ah!

I could not find that in the docs. That makes sense but I could still use 
an example?

  *This is your app "test.py"
*
from flask import *
app = Flask(__name__)

@app.route('/index/')
def index():
     return render_template('index.html')

if __name__ == '__main__':
     app.run('0.0.0.0', debug=True)

*And this is your template "./templates/index.html"
*
<div>Arguments</div>
<ul>
     {% for key,value in request.args.items() %}
<li>{{ key }} = {{ value }}</li>
     {% endfor %}
</ul>

`request.args`[1] is basically a `werkzeug.MultiDict`[2], so this may
not show every value. If you use `.lists()` or `.iterlists()` instead
you don't have that problem.

  That's really useful to know. Thanks.
