For backward compatibility, when Python is invoked with the \code{-X}
option, most of the standard exceptions are strings\footnote{For
-forward-compatibility the new exceptions \code{LookupError},
-\code{ArithmeticError}, \code{EnvironmentError}, and
-\code{StandardError} are tuples.}. This option may be used to
+forward-compatibility the new exceptions \exception{LookupError},
+\exception{ArithmeticError}, \exception{EnvironmentError}, and
+\exception{StandardError} are tuples.}. This option may be used to
run code that breaks because of the different semantics of class based
exceptions. The \code{-X} option will become obsolete in future
Python versions, so the recommended solution is to fix the code.
empty string if no arguments were given to the constructor. When used
as a sequence, this accesses the arguments given to the constructor
(handy for backward compatibility with old code). The arguments are
