Why does the interactive prompt not recognize escape sequences in

That depends on how you define "correctly"...
When you evaluate an expression at the Python prompt Python prints the
repr() of the value. For strings that includes the quotes and the \n
characters and any other special characters it finds. The print
function on the other hand prints the str() of the value and that
interprets the quotes etc out
In general repr() is more useful for debugging since it shows any
'hidden' whitespace characters. repr() by convention should return a
value that can be evaluated and assigned to a variable, although it
doesn't always do that for miore complex types.
