入参介绍

def find_all(predicate):
   """
   Lets you find all occurrences of the given GUI element predicate. For
   instance, the following statement returns a list of all buttons with label
   "Open"::

      find_all(Button("Open"))

   Other examples are::

      find_all(Window())
      find_all(TextField("Address line 1"))

   The function returns a list of elements of the same type as the passed-in
   parameter. For instance, ``find_all(Button(...))`` yields a list whose
   elements are of type :py:class:`Button`.

   In a typical usage scenario, you want to pick out one of the occurrences
   returned by :py:func:`find_all`. In such cases, :py:func:`list.sort` can
   be very useful. For example, to find the leftmost "Open" button, you can
   write::

      buttons = find_all(Button("Open"))
      leftmost_button = sorted(buttons, key=lambda button: button.x)[0]
