There's a hint in the sample/multicolumnexample.py in the comments at 
the head.
Playing around a bit with that, I think you pass in a list like
   [ ["header", width, format], ...]
width is an integer value :
    -1 = auto_size
    positive value is an actual column width
(note you must have ALL columns set to auto_size to get autosizing)

format is one of
   wxLIST_FORMAT_LEFT        : 0
   wxLIST_FORMAT_RIGHT     : 1
   wxLIST_FORMAT_CENTRE  : 2

 
Here's a snippet from my "play" code version of multicolumnexample.py
(from on_loadButton_mouseClick

I changed

>         self.components.theList.items = items[1:]

to

P.S. I couldn't figure out the right way to use the wxLIST_FORMAT_*  
constants. I'm sure you should be able to do something like
 import wx
and then use wx.wxLIST_FORMAT_LEFT
but that didn't work - I finished up doing
import wx
print wx._controls.wxLIST_FORMAT_LEFT
to check what the values were.
