Actually, this doesn't work. The string you show has two characters,
both of them backslashes. The r prefix means that backslashes aren't
escapes, they're literal backslash characters. Unfortunately, there's a
flaw in the Python lexer which means you can't use a single backslash
here either:
>>> r'\\'
'\\\\'
>>> r'\'
File "<stdin>", line 1
r'\'

SyntaxError: EOL while scanning single-quoted string
