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
Run where a
is input array and c
is a constant. b
is the resultant array.
Example
In the following python example, we will add a constant 3
to an array a
. The resulting array is stored in b
.
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)
