How to slice all the columns except first column in numpy array?

Question

I am trying to slice the columns of numpy array in python.

How to print all the columns except first one? Imagine I have large dimensions of numpy array not the simple one.

First, create an array in Python, then, use slicing to extract everything but the first column:

import numpy as np
a = np.array([[1,2,3], [4,5,6], [7,8,9]])
sliced = a[:,1:]
print(sliced)

output:

array([[2, 3],
       [5, 6],
       [8, 9]])
