Add items from one list to list of lists
#1
Hello,

I would like to add every element of a list on every list from a list of lists. Ie :
H = [[1,2],[3,4]]
I = [5,6]
With this result :
Output:
J = [[1,2,5], [3,4,5], [1,2,6], [3,4,6]]
I don’t find the good logic.

Ie :
j = []
for x in h :
	for y in i :
		j.append(h+i)
		print (j)
Gives me :

Output:
[[[1, 2], [3, 4], 5, 6]] [[[1, 2], [3, 4], 5, 6], [[1, 2], [3, 4], 5, 6]] [[[1, 2], [3, 4], 5, 6], [[1, 2], [3, 4], 5, 6], [[1, 2], [3, 4], 5, 6]] [[[1, 2], [3, 4], 5, 6], [[1, 2], [3, 4], 5, 6], [[1, 2], [3, 4], 5, 6], [[1, 2], [3, 4], 5, 6]]
Or again :

k = []
for w in h :
	for z in i :
		o = [w,z]
		k.append(o)
		print (k)
Will give :

Output:
[[[1, 2], 5]] [[[1, 2], 5], [[1, 2], 6]] [[[1, 2], 5], [[1, 2], 6], [[3, 4], 5]] [[[1, 2], 5], [[1, 2], 6], [[3, 4], 5], [[3, 4], 6]]
I’ve tried some tests with map, but nothing conclusive.

Can you help me please to solve my problem ?
