I made my original little test case program as short
as possible. I know that normally I have to
call the constructor of the class I inherit from.

The two problems are the pylint messages:

 Module 'wx' has no 'Platform' member
 Too many public methods (259/20)

The first one is simply untrue, the second one
complains abouth something which is outside my control.

These problems remain if I call the wx.Frame.__init__
method.

Just to keep the focus on the actual problems,
here is a version of my test case program that
changes all the things that I _can_ change,
but still gets the two error messages from pylint:


hp/py> cat test_wx_platform.py
" a pylint test. "
__revision__ = '2'

import wx

class Test(wx.Frame):
   """
      This class has only one method,
      but gets a Too many public methods
      error from pylint.
   """
   def __init__(self):
      wx.Frame.__init__(self, None)
      # wx.Platform does exist, but pylint says it does not.
      print wx.Platform

app = wx.PySimpleApp()
Test()
hp/py> python test_wx_platform.py
__WXGTK__
hp/py> pylint test_wx_platform.py
************* Module test_wx_platform
E: 15:Test.__init__: Module 'wx' has no 'Platform' member
R:  6:Test: Too many public methods (259/20)
