test for raw string

[John Hunter]

I have a function that takes a string as an argument. Is there a way
to test whether the caller of this function passed in a raw string

def func(s):
if israw(s): do_x()
else: do_y()

func(r'\hi mom') # do_x
func('hi mom') # do_y

Thanks,
John Hunter

A raw string is a feature of the syntax at compile time. You cannot
distinguish a raw string any more than you can distinguish "hi mom" and 'hi
mom'. The type of quotes, whether it was single or triple quoted, and
whether it was raw or normal are simply aspects of the syntax.

No. Those are just two different ways of writing the same string.
It's like asking func(3.0) and func(3.00) to do two separate things.
