This is more about the quiz itself, what is a processor variable? 

What do you mean when you say the base template in the starter code has two placeholders?  I assume page_title is one placeholder, because the value of message is assigned when base.html is rendered.  Is the messages variable another placeholder, even though the value of the messages variable is assigned inside the html file?

Can you please review how all the parts in POST-REDIRECT-GET tie in together?

Can you go over the why we render a blank form if method is get in the one route section?

"Can you explain the 
{% if msg %}
<p>{{msg}}</p>
{% endif %}
 in example_form_processing_one_route.py?"

Is the one-route concept essentially allowing both get & post with the same template?

Why does refreshing cause re-submission? I thought for most (if not all) forms, there is some type of submit button? Also the browser tries to prevent resubmission because the data is already cached so it doesn't want to "do it again"?

Not a question, but I wanted to add that I also find these readings that run through chunks of code to be very helpful.  I also think the recorded demo of it working would be helpful if possible.

Is app.config['TRAP_BAD_REQUEST_ERRORS'] generalizable to code outside of the Wellesley CS server?  Can you review what a website looks like with and without it?
