sorting 2D lists by column

[ToffieFaye]

Hello everyone,

I would like to sort a multidimensional list by the second column.

Example:

x = [
    [1,18,2],
    [2,9,4],
    [3,1,1]
    ]

x = sorted(x, key=lambda x: x[2])
print(x)

The output I am looking for should be:

[
[3,1,1],
[2,9,4],
[1,18,2]
]

Unfortunately lamdba sorts like this:

[
[3,1,1],
[1,18,2],
[2,9,4]
]

So lamda does put 18 below 9, because of the '1' in the front.
I did try numpy arrays too, but I just can't find the right way.
Can anyone help me with this problem?

thank you very much!
