Why can the number_of_characters variable be used again and again? Don't you have to use a diff term for diff 'advices'?

Each 'advice' had a variable called number_of_characters. If it was used the first time I get it, but when it was used the second time, wouldn't the program use the int obtained from len in the first 'advice'? Not sure if you get me.

The line of code that uses "len" to set the "number_of_characters" comes right before the line that uses that value for the output. So for every message, these are both done, giving "number_of_characters" a fresh value.

If you could clarify this, I have the same question but was thrown off by the "result =" variable. Being that variables are immutable, I didn't think that it would print more than one variation of the result variable. Is there something about using a variable in a certain way that actually makes it reference something else? Is this an order of operations kind of thing?

Thanks!
