How to get specific row from Numpy array

import numpy as np
arr = np.array([[1, 2], [3, 4]])
row = arr[1,:]

import numpy as np - load lib:Numpy module for Python
[[1, 2], [3, 4]] - sample matrix data (2-dimensional array)
np.array - declare Numpy array
arr - variable contains array
[1,:] - return second row (index number is 1) of the specified matrix

group: get_row

Example:

import numpy as np
arr = np.array([[1, 2], [3, 4]])
row = arr[1,:]
print(row)
