Calculate The Sum Of Each Column In An Array Using NumPy.

In this python numpy program, we will calculate the sum of each column in an array using NumPy.

Import the numpy library as np.
Create an array using np.array().
Use np.sum() and set the axis equal to 0 to calculate the sum of each column in an array.
Print the output.

				
					import numpy as np
x = np.array([[5, 3],
              [7, 4]])
print("Sum of each column : ",np.sum(x,axis=0))

Output :

				
					Sum of each column :  [12  7]
