ok, I have found partially an answer:

listoflists = []
a_list = []
for i in range(0,x):
a_list.append(i)
if len(a_list)>0:

listoflists.append(list(a_list))
print listoflists
a = listoflists

this prints me this:

[[0], [0, 1], [0, 1, 2], [0, 1, 2, 3], [0, 1, 2, 3, 4], [0, 1, 2, 3, 4, 5], [0, 1, 2, 3, 4, 5, 6], [0, 1, 2, 3, 4, 5, 6, 7]]

this is what I wanted but how to convert this to tree in grasshopper?

In grasshopper I just get:

8x IronPython.Runtime.List

I had a similar problem. This thread summed up the solution:
