Is there a direct function in python to normalise values in a single column of a matrix?

Is there a function in any python library by which I can normalize certain columns of a matrix independently? For instance: 

1 2 3
1 2 4
1 2 5

if I want a transformation of the above matrix to 

1 1 3
1 1 4
1 1 5

i.e normalize the values in the 2nd column.

Thanks in advance.

Yes,

You can use np.linalg.norm
