python: escape all escaped characters

I need to doubly escape all escaped characters in a string in python. So, for example, any instances of '\n' need to be replaced by '\\n' I can easily do this one character at a time with

s = s.replace('\n', '\\n')
s = s.replace('\r', '\\r')
# etc...

But I'm wondering if there's a one-off way to handle all of them.

repr returns the string representation of a string... which sounds redundant except that it double-escapes escape characters like you would if you typed them in yourself. It also encloses the string in quotes, but that can be easily removed.

>>> repr('\n\t\r')[1:-1]
'\\n\\t\\r'
