4.1 Standard Exceptions 
All standard Python exceptions are available as global variables whose
names are "PyExc_" followed by the Python exception name.  These
have the type PyObject*; they are all class objects.  For
completeness, here are all the variables:
  
    
      | C Name | Python Name | Notes | 
    
  
    | PyExc_Exception | Exception | (1) | 
    | PyExc_StandardError | StandardError | (1) | 
    | PyExc_ArithmeticError | ArithmeticError | (1) | 
    | PyExc_LookupError | LookupError | (1) | 
    | PyExc_AssertionError | AssertionError |  | 
    | PyExc_AttributeError | AttributeError |  | 
    | PyExc_EOFError | EOFError |  | 
    | PyExc_EnvironmentError | EnvironmentError | (1) | 
    | PyExc_FloatingPointError | FloatingPointError |  | 
    | PyExc_IOError | IOError |  | 
    | PyExc_ImportError | ImportError |  | 
    | PyExc_IndexError | IndexError |  | 
    | PyExc_KeyError | KeyError |  | 
    | PyExc_KeyboardInterrupt | KeyboardInterrupt |  | 
    | PyExc_MemoryError | MemoryError |  | 
    | PyExc_NameError | NameError |  | 
    | PyExc_NotImplementedError | NotImplementedError |  | 
    | PyExc_OSError | OSError |  | 
    | PyExc_OverflowError | OverflowError |  | 
    | PyExc_ReferenceError | ReferenceError | (2) | 
    | PyExc_RuntimeError | RuntimeError |  | 
    | PyExc_SyntaxError | SyntaxError |  | 
    | PyExc_SystemError | SystemError |  | 
    | PyExc_SystemExit | SystemExit |  | 
    | PyExc_TypeError | TypeError |  | 
    | PyExc_ValueError | ValueError |  | 
    | PyExc_WindowsError | WindowsError | (3) | 
    | PyExc_ZeroDivisionError | ZeroDivisionError |  | 
Notes:
- (1)
- This is a base class for other standard exceptions.
 
- (2)
- This is the same as weakref.ReferenceError.
 
- (3)
- Only defined on Windows; protect code that uses this by testing that
  the preprocessor macro MS_WINDOWSis defined.
