Program to make an array immutable using NumPy

by

In this python numpy program, we will make an array immutable using NumPy.

Steps to solve the program
  1. Import the numpy library as np.
  2. Create an array using np.array().
  3. Make an array immutable i.e. read-only by setting flags.writeable as False.
  4. When we try to change any value of the array it will show the error as
    ValueError: assignment destination is read-only.

				
					import numpy as np
x = np.array([[5, 3],[7, 4]])
x.flags.writeable = False
x[0,1] = 0

Output :

				
					ValueError                                Traceback (most recent call last)
<ipython-input-6-6fe1d7a57604> in <module>
      3 x = np.array([[5, 3],[7, 4]])
      4 x.flags.writeable = False
----> 5 x[0,1] = 0

ValueError: assignment destination is read-only
Previous

find the median of the matrix along the column.

Next

print every element of an array.
