SWIG is smart enough to recognize that C++ operators == and != mean __eq__ and __ne__ in Python and do the appropriate translation
But it is not smart enough to recognize that mySBObject == None should return False instead of erroring out
The %pythoncode blocks are meant to provide those extra smarts (and they play some SWIG&Python magic to find the right function to call behind the scenes with no risk of typos :-)
Lastly, SBBreakpoint provides an == but never provided a != operator - common courtesy is to provide both
