Python combination and permuation code -


i have following code generate set of combination, append combination in list, , return list.

def make_combination():   import itertools     max_range = 5    indexes = combinations_plus = []   in range(0, max_range):      indexes.append(i)     in xrange(2, max_range):        each_combination = [list(x) x in itertools.combinations(indexes, i)]       combinations_plus.append(each_combination)   retrun combinations_plus

it generates many combinations don't want (hard display). but, want following combination:

1) [[0, 1], [0, 2], [0, 3], [0, 4], [1, 2], [1, 3], [1, 4], [2, 3], [2, 4], [3, 4]]

2) [[0, 1, 2], [0, 1, 3], [0, 1, 4], [0, 2, 3], [0, 2, 4], [0, 3, 4], [1, 2, 3], [1, 2, 4], [1, 3, 4], [2, 3, 4]]

3) [[0, 1, 2, 3], [0, 1, 2, 4], [0, 1, 3, 4], [0, 2, 3, 4], [1, 2, 3, 4]]

i think problem in following line don't know is. idea mistake is.

combinations_plus.append(each_combination)

an easier way of doing want following:

list(list(itertools.combinations(list(range(5)), i)) in range(2, 5))
