Replace Elements with Zeros in Python | Assignment Expert

Today, we will see how to replace elements with zeros in Python. We will write two programs for that, in the first one, we will see how to replace elements with zeros in a matrix created using lists in Python, and in the second one, we will use NumPy.

1. Replace Elements with Zeros in a matrix of List in Python

matrix = [[1, 2, 3],
          [4, 5, 6],
          [7, 8, 9]]

for i in range(len(matrix)):
    for j in range(len(matrix)):
        matrix[i][j] = 0
        
print(matrix)

Output:

2. Replace Elements with Zeros in a matrix of List in Python

import numpy as np

matrix = np.array([[1, 2, 3],
          [4, 5, 6],
          [7, 8, 9]])

for i in range(len(matrix)):
    for j in range(len(matrix)):
        matrix[i][j] = 0
        
print(matrix)

Output:
