try:
    ...
except AssertionError:
    ...

OTOH, the idea is that assertion errors are raised when a method's 
contract is violated, i.e. you assume that AssertionError will never be 
raised when there are no bugs. Given this proper use of assertions, they 
are the wrong construct here and if ...: raise FooError(msg) should be 
used (where FooError is the exception class).
