Raw string substitution problem

[Ed Keith]

I am having a problem when substituting a raw string. When I do the following:

re.sub('abc', r'a\nb\nc', '123abcdefg')

I get

"""
123a
b
cdefg
"""

what I want is

r'123a\nb\ncdefg'

How do I get what I want?

Thanks,

Looks like raw strings lets you avoid having to escape slashes when
specifying the literal, but doesn't preserve it during operations.
changing your replacement string to r'a\\nb\\nc' seems to give the
desired output
