break on unhandled exception in pycharm

I'm new in Python and I'm trying to debug my first python program using PyCharm 1.5. I want debugger to break when exception occurs in my code (and only in mine).

For now the situation is following: I use (Ctrl + Shift + F8 ) Dialog to configure debugger and If i set Suspend All = true and All exceptions = true then debugger breaks far too often, for example, it breaks somewhere inside PyCharm 1.5.1\hel开发者_运维知识库pers\pydev\pydevd.py which is annoying to skip every time. And if I set any other options then debugger does not break even when exception occurs in my code.

PS: By the way, if I just skip breaks in PyCharm 1.5.1\helpers\pydev\pydevd.py then execution continues without visible errors. So I do not understand why it breaks at all

One way to tell apart your exceptions from exceptions coming from a library, is to have them derive from a custom class, e.g. if your module is called Foo, you could have

class FooException(Exception):
   pass

and have more specific exceptions derive from this:

class MyMathException(FooException):
   # etc.

Then, in PyCharm, instead of enabling All Exceptions, add FooException to the list of exceptions to break upon.
