Create a 2×2 zero matrix with elements on the main diagonal equal to numbers

In this python numpy program, we will create a 2×2 zero matrix with elements on the main diagonal equal to numbers.

Import the numpy library as np.
Create a 2×2 zero matrix with elements on the main diagonal using np.diag().
Print the output.

				
					import numpy as np
x = np.diag([7,8])
print(x)

Output :

				
					[[7 0]
 [0 8]]

reshape the 2×3 matrix into a 2×2 matrix.

calculate the sum of all elements in an array.
