Python Python Basics Functions and Looping Raising Exceptions

Why is there a "(could not convert string to float: 'l')" message

I don't understand why when you input a string into the "What is the total? " question you also get this message (could not convert string to float: '#whatever your input was'). Shouldn't it be just the "Oh no! That's not a valid value. Try again..." message??

The ValueError: could not convert string to float: 'I' is being raised by Python to indicate what the error is to the developer. "Oh no! That's not a valid value. Try again..." is for the user.

In the video Craig says at the 3:10 mark or so:

"you can get a reference to the exception that was raised And you can do this with a new keyword that's called as, so you say except ValueError as error, we'll just call it err."
