Functions

• concat(lists)

  Concatenate a list of lists.

  >>> concat(range(i) for i in range(5))
  [0, 0, 1, 0, 1, 2, 0, 1, 2, 3]
  >>> concat([[1,2], [3]])
  [1, 2, 3]
  >>> concat([[1,2,[3,4]], [5,6]])
  [1, 2, [3, 4], 5, 6]
  >>> concat([])
  []
  

• disjoint(*sets)

  Test whether a collection of sets is pair-wise disjoint.

  >>> disjoint(set([1,2]), set([3]))
  True
  >>> disjoint(set('abc'), set('xy'), set('z'), set('cde'))
  False
  >>> disjoint()
  True
  

• intersect(sets)

  Intersect a non-empty collection of sets.

  >>> intersect([set('ab'), set('bc'), set('bb')])
  set(['b'])
  >>> intersect([set('ab'), set('bc'), set('ac')])
  set([])
  >>> try: intersect([])
  ... except: print 'bad'
  ...
  bad
  

• is_sequence(x)
• union(sets)

  Union a collection of sets.

  >>> union([set('ab'), set('bc'), set('ac')]) == set('abc')
  True
  >>> union([])
  set([])
