Numpy Array – Divide all elements by a constant
Dividing a NumPy array by a constant is as easy as dividing two numbers. To divide each and every element of an array by a constant, use division arithmetic operator /
. Pass array and constant as operands to the division operator 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 divide array a by a constant 3
. 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)
#divide all the elements of array by constant
b = a / 3
print("\nAfter dividing by a constant\n",b)
