.. attribute:: args
The tuple of arguments given to the exception constructor. Some built-in
- exceptions (like :exc:`IOError`) expect a certain number of arguments and
+ exceptions (like :exc:`OSError`) expect a certain number of arguments and
assign a special meaning to the elements of this tuple, while others are
usually called only with a single string giving an error message.
