How to create an array from two columns in pandas

You can also achieve the same output with the below code.

import numpy as np
np.array(df[['col1','col2']])
Out[60]: 
array([[0, 1],
       [2, 3],
       [4, 5]])

You can access the underlying numpy array via the to_numpy method:

df[['col1', 'col2']].to_numpy()
Out: 
array([[0, 1],
       [2, 3],
       [4, 5]])

.values attribute will do the same if you are on an earlier version (before v0.24).
