How can get a part of a 2D array?

Question

I have a 2d array with shape (100, 64). I need to obtain a new array like (100, 63), just like deleting one column from a sheet. So what numpy function should I use to obtain this?

# Let X be my (100, 64) dataset, and i the column I want to delete
np.somefunction(X[:, :i], X[:, i:])

You can use delete:

np.delete(X, i, axis=1)

or hstack:

np.hstack((X[:, :i-1], X[:, i:])
