paths = ['/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'
]
seen = set()
basepaths = [ seen.add(s) or s for s in paths
if not any(s.startswith(ss) for ss in seen) ]
gives:
['/notebook', '/desktop', '/server/hp/proliant']
