12.17.3 Exceptions

Exceptions in this module are coded as class instances:

exception `Error`
  The base exception class. `Error` has a single public data member `msg` containing the description of the error.

exception `ConversionError`
  Class derived from `Error`. Contains no additional instance variables.

Here is an example of how you would catch one of these exceptions:

      import xdrlib
      p = xdrlib.Packer()
      try:
          p.pack_double(8.01)
      except xdrlib.ConversionError, instance:
          print 'packing the double failed:', instance.msg
