So I've got a 3-dimensional numpy array and I want to insert into it a 1-dimensional numpy array. How can I do it?
For example, this is my 3D array and I want to insert [2,2,2]
[[[1,1,1],
[3,3,3],
[4,4,4]],
[[5,5,5],
[6,6,6],
[7,7,7]]]
so it looks like this:
[[[1,1,1],
[2,2,2],
[3,3,3],
[4,4,4]],
[[5,5,5],
[6,6,6],
[7,7,7]]]
How can I do it?
You cannot do this with standard numpy arrays as they must remain rectangular. Potentially, you could create one with dtype=object, but this seems to me like you would lose the efficiency of numpy.
Maybe you are better off with regular lists?
l = [[[1,1,1],
[3,3,3],
[4,4,4]],
[[5,5,5],
[6,6,6],
[7,7,7]]]
l[0].insert(1, [2,2,2])
which modifies l to:
l = [[[1,1,1],
[2,2,2],
[3,3,3],
[4,4,4]],
[[5,5,5],
[6,6,6],
[7,7,7]]]
