except MySQLdb.Error, e:
print "An error has been passed. %s" %e

For exceptions see:
http://python.about.com/od/pythonstandardlibrary/a/lib_exceptions.htm
For warnings visit:

The Python documentation also covers them at:
http://docs.python.org/library/exceptions.html

Each of the previous types can be caught with the DatabaseError type. However, catching them separately allows you to customize responses. For example, you may want the application to fail softly for the user when a ProgrammingError is raised but nonetheless want the exception to be reported to the development team. You can do that with customized exception handling.
