[Gimp-user] Python-fu : how to remove layers ?

[chaouche yacine <yacinechaouche yahoo com>]

Hello. I have a gif animation that has 190 layers. It's a too much. I want to remove one out of three layers 
via the python-fu console. Here's what I did : 

> > > image = gimp.image_list()[0]
> > > image.layers = [layer for (index,layer) in enumerate(image.layers) if index  % 3]
Traceback (most recent call last):
  File "<input>", line 1, in <module>
AttributeError: attribute 'layers' of 'gimp.Image' objects is not writable
> > >

What is the correct way of removing layers ?

Thanks for you help in advance.
