List of paths

[Nico Grubert]

Dear Python developers

I have the following (sorted) list.
['/notebook',
  '/notebook/mac',
  '/notebook/mac/macbook',
  '/notebook/mac/macbookpro',
  '/notebook/pc',
  '/notebook/pc/lenovo',
  '/notebook/pc/hp',
  '/notebook/pc/sony',
  '/desktop',
  '/desktop/pc/dell',
  '/desktop/mac/imac',
  '/server/hp/proliant',
  '/server/hp/proliant/385',
  '/server/hp/proliant/585'
]

I want to remove all paths x from the list if there is a path y in the 
list which is part of x so y.startswith(x) is true.

The list I want to have is:
['/notebook', '/desktop', '/server/hp/proliant']

Any idea how I can do this in Python?

Thanks in advance
Nico
