Creating sequential sublists from a list

I'm new here and to programming as well.

I don't know if I put the question right, but I have been trying to generate sublists from a list.

i.e

say if L = range(5), generate sublists from L as such [[],[0],[0,1],[0,1,2],[0,1,2,3],[0,1,2,3,4]].

Kindly assist. Thanks.

Solution

  • Look at this:

    >>> # Note this is for Python 2.x.
>>> def func(lst):
...     return map(range, xrange(len(lst)+1))
...
>>> L = range(5)
>>> func(L)
[[], [0], [0, 1], [0, 1, 2], [0, 1, 2, 3], [0, 1, 2, 3, 4]]
>>>
