Numpy Array – Add a constant to all elements of the array
Adding a constant to a NumPy array is as easy as adding two numbers. To add a constant to each and every element of an array, use addition arithmetic operator
+. To addition operator, pass array and constant as operands as shown below.
b = a + c
a is input array and
c is a constant.
b is the resultant array.
In the following python example, we will add a constant
3 to an array
a. The resulting array is stored in
import numpy as np #2D array a = (np.arange(8)*2).reshape(2,4) #print array print("The array\n",a) #adding a constant to all the elemnets of array b = a + 3 print("\nAfter adding a constant to all the elemnets of array\n",b)
