No, they all work the same way (thank goodness!).  The "." between "wx"
and "frame" is the same dot as is between "random" and "choice" (i.e.,
random.choice is the same construct as wx.frame).

Don't be confused by from:  if you use "from wx import frame," then you
can access frame *without* the "wx." bit.  I don't have wx installed,
but that works with random, too:

    >>> choice
    Traceback (most recent call last):
      File "<stdin>", line 1, in ?
    NameError: name 'choice' is not defined
    >>> import random
    >>> random.choice
    <bound method Random.choice of <random.Random object at 0x1841a10>>
    >>> from random import choice
    >>> choice
    <bound method Random.choice of <random.Random object at 0x1841a10>>

HTH,
Dan
