 The \code{operator} module exports a set of functions implemented in C
 corresponding to the intrinsic operators of Python.  For example,
-{}\code{operator.add(x, y)} is equivalent to the expression x+y.  The
+{}\code{operator.add(x, y)} is equivalent to the expression \code{x+y}.  The
 function names are those used for special class methods; variants without
