The meanings of these are explained at:
https://docs.python.org/library/re.html#regular-expression-syntax

Outside of multiline mode, they're equivalent. In multiline mode, ^
and $ will also match at the beginning and end of individual lines,
while \A and \Z still only match the beginning and end of the input
string.
