NumPy – Divide all elements in array 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
a is input array and
c is a constant.
b is the resultant array.
In the following python example, we take an array in
a, and divide this array by a constant
3. The resulting array is stored in
b, and print to the standard output.
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)
In this Numpy Tutorial of Python Examples, we learned how to divide elements in a numpy array by a constant.
