    Unicode raw string containing \u

    I'm trying to write a unicode raw string literal, and I seem to be
    running up against a conflict between the \uXXXX unicode character
    escape and the need to have a literal \u (i.e., backslash followed by a
    lowercase letter U) in the string.

    If I do ur"\universe" I get a UnicodeDecodeEr ror because (I think)
    it tries to interpret \universe as a Unicode escape. But if I do
    ur"\\universe " I get a string that contains two backslashes followed by
    the word "universe".

    How can I specify a unicode raw string literal that contains a
    single backslash followed by the word "universe"?

      That's because in a raw string, \\ means two backslashes.

      The usual way.
      >>word = u'\\universe'
      >>len(word)
      9
      >>word[0]
      u'\\'
      >>word[1]
      u'u'
      >>print word
      \universe
      >>word
      u'\\universe'

          That doesn't answer my question, since I asked for a unicode RAW
          string literal. Is this not possible? (I was able to get what I want
          using ur"\u005Cuniver se", although this is not totally ideal.)

              It's a design flaw in Unicode raw string literals that they still
              interpret \u escapes. And yes, your notation is one way to get what
              you want; another is u"\\"+r"univers e", although I'm unsure whether
              that meets your requirements.
