sure, and `else` is used for a clause that is to be executed when the 
main condition of `if` is false.

So, in

    try:
        do_something
    except:
        catch_exception
    else:
        continue_doing_something

when no exception occurs in `do_something`, is `do_something` more 
true, or more false?
