Confused about lesson question

Question

I am confused as to why \AS...\b.\Z should match 'SPAM!' in search. I understand the \A looks for the beginning and the S is there so that's a match, and what the \b does it ok, but since there is a '.' and not '!' at the end, then how come \Z is matching '.' and '!' ?? Totally lost.

Answer 1

. is used to match anything (character/space).

And
! Is used to say the last letter of string
