Python, How to fill up a column in an empty numpy array

Question

I would normally go to

http://docs.scipy.org

for this info but their website is down for some reason:/

But how would I be able to fill up an entire column in a numpy matrix?

a = numpy.zeros(shape=(100,10))
a[0] = [1,2,3,4,5,6,7,8,9,0]

fills up a row, but how can you do a column?

a[:, k] = values. You would have found that in any NumPy tutorial. — Fred Foo

@SaulloCastro You may post it if you want, I'm not interested in this basic stuff. — Fred Foo

This fills the same value in all columns:

  array[:, column] = values

The question was how to fill up an entire column, not how to fill all columns with the same value.
