A list containing \var{StringType} and \var{UnicodeType} used to

A sequence containing \code{StringType} and \code{UnicodeType} used to
facilitate easier checking for any string object. Using this is more
portable than using a sequence of the two string types constructed
elsewhere since it only contains \code{UnicodeType} if it has been
built in the running version of Python. For example:
\code{isinstance(s, types.StringTypes)}.
