    Exception Handling In DTML - Pre-Packaged Python


    (Page 9 of 10 )

    There are a number of standard exceptions are built into Python (and, therefore, Zope and DTML). Here they are:

    IOError - generated when an I/O operation fails;

    ImportError - generated when a module import fails;

    IndexError - generated when an attempt is made to access a non-existent element index;

    KeyError - generated when an attempt is made to access a non-existent dictionary key;

    MemoryError - generated when an out-of-memory error occurs;

    NameError - generated when an attempt is made to access a non-existent variable;

    SyntaxError - generated when the interpreter finds a syntax error;

    TypeError - generated when an attempt is made to run an operation on an incompatible object type;

    ZeroDivisionError - generated when an attempt is made to divide by zero.

    For a complete list, take a look at http://www.python.org/doc/current/lib/module-exceptions.html
