Why has python3 been created as a seperate language where there is still python2.7 ?

Alas, not perfectly so. A 'bytes' object and a 'unicode' object can be
described that way (with 'str' an alias for one or t'other), but
literal strings are never that simple. (Backslash escapes, delimiters,
newlines, etc, etc, etc.) However, it is a nice idea, to the extent
that it's possible.
