Currently the below code generates the following graph, giving a complexity of 5:

def f():
    try:
        print(1)
    except TypeA:
        print(2)
    except TypeB:
        print(3)
    else:
        print(4)
    finally:
        if x:
            print(5.1)
        else:
            print(5.2)

I don't think this models the try-else clause correctly. The above graph seems to indicate that the else sometimes runs instead of the main clause, which isn't correct. I believe this is the correct model:

This seems to correctly indicate that the else always runs directly after the main try clause, if it runs, and never in a line of execution that involves the exception handlers. This has 1 less complexity than the above graph. This yields one less complexity than the current interpretation.
