Multiple the number to matrix in Numpy Python by R4R Team

Task-
In the given array or matrix, we have to multiple a number in each elements of the array.

Example-

array is [1 2 3 4]
then array*2 will give [2 4 6 8]


program-

#import numpy
import numpy as np

l=[1,2,3,4,5]
arr=np.array(l)
print("Matrix is :",arr)
print("After Multiple 2 :",arr*2)

l=[[1,2,3],[4,5,1],[1,1,0]]
arr=np.array(l)
print("nMatrix is :n",arr)
print("After Multiple 3 :n",arr*3)


output-

Matrix is : [1 2 3 4 5]
After Multiple 2 : [ 2 4 6 8 10]

Matrix is :
[[1 2 3]
[4 5 1]
[1 1 0]]
After Multiple 3 :
[[ 3 6 9]
[12 15 3]
[ 3 3 0]]

-In this program, we create a array from the list then multiple number to every element of the array and display them.
