r"^1..3

Answer 1

Read Regular Expression in python course

Answer 2

Dragon Wolf you raised a good question.
It seems like they have the same function when we used them in regular expression. However, they differ in matching multiple lines.

^ can match at the start of the string and after each line break.

\A only ever matches at the start of the string

$ can match at the end of the string and before each line break.

\Z only ever matches at the end of the string.
