Flask Basics - Forms - KeyError: 'name'

for anyone wondering why they are getting a 'wekzeug.exceptions.badrequestkeyerror' in the demonstration, the teach uses the print function to call the form['name'] inside the add_pet() function.

this is done when the page is already loaded, and there is a form['name'] to access. If you reload your page, you will get an error.

This was likely done as a demonstration on how you could access the data, not anything you would do in the real world.

You will need to comment out the print to load the page again

Great clarification! You're exactly right! It's a great way to play around and see what's happening but you wouldn't want those print statements in there with a live website.
