You can do this almost automatically with a decorator:

def in_try(func):
    def wrapper(*args, **kwargs):
        try:
            return func(*args, **kwargs)
        except:
            print "entered except"
            raise
    return wrapper

class C(object):
    @in_try
    def func_a(self):
        print "func_a"
        
    @in_try
    def func_b(self):
        print "func_b"
        raise Exception

You could probably create a metaclass to apply the wrappers automatically but I like having it explicit as above.
