It seems the parser is interpreting the backslash as an escape
character in a raw string if the backslash is the last character.
Is this expected?
Yep...as documented[1], "even a raw string cannot end in an odd number
of backslashes".
So how do you explain this?
>>> r'a\'b'
"a\\'b"
The backslash is kept, but it causes the following quote to be escaped.
(The following examples are from Python 2.x.)
The other special case is with \u in a Unicode string:
>>> ur"\u0041"
u'A'
However, \x isn't special:
>>> ur"\x41"
u'\\x41'
and \u isn't a recognised escape sequence in a bytestring:
>>> r"\u0041"
'\\u0041'
