  # numpy.multiply () in Python

Arrays | NumPy | Python Methods and Functions

`numpy.multiply()` is used when we want to compute the multiplication of two arrays. Returns the product of arr1 and arr2 element by element.

Syntax: numpy.multiply (arr1, arr2, /, out = None, *, where = True, casting = `same_kind `, order =` K `, dtype = None, subok = True [, signature, extobj], ufunc` multiply `)

Parameters:
arr1: [array_like or scalar] 1st Input array.
arr2: [array_like or scalar] 2nd Input array.
dtype: The type of the returned array. By default, the dtype of arr is used.
out: [ndarray, optional] A location into which the result is stored.
- & gt ; If provided, it must have a shape that the inputs broadcast to.
- & gt; If not provided or None, a freshly-allocated array is returned.
where: [array_like, optional] Values ​​of True indicate to calculate the ufunc at that position, values ​​of False indicate to leave the value in the output alone.
** kwargs: Allows to pass keyword variable length of argument to a function. Used when we want to handle named argument in a function.

Return: [ndarray or scalar] The product of arr1 and arr2, element-wise.

Code # 1:

 ` # Python program explaining ` ` # numpy.multiply () function `   ` import ` ` numpy as geek ` ` in_num1 ` ` = ` ` 4 ` ` in_num2 ` ` = ` ` 6 `   ` print ` ` (` ` "1st Input number:" ` `, in_num1) ` ` print ` ` (` `" 2nd Input number: "` `, in_num2) `   ` out_num ` ` = ` ` geek.multiply (in_num1, in_num2) ` ` print ` ` (` ` "output number:" ` `, out_num) `

Output:

``` 1st Input number: 4 2nd Input number: 6 output number: 24     Code # 2:            ` # Python program explaining `  ` # numpy.multiply () function `      ` import ` ` numpy as geek  ``      in_arr1   =   geek.array ([[  2  ,   -   7  ,   5  ], [  -   6   ,   2  ,   0  ]])    in_arr2   =   geek.array ([[  0  ,   -   7  ,   8  ], [  5  ,   -   2  ,   9  ]])       print   (  "1st Input array:"  , in_arr1)    print   (  "2nd Input array:"  , in_arr2)           out_arr   =   geek.multiply (in_arr1, in_arr2)    print   ( " Resultant output array: " , out_arr) `   Output:    1st Input array : [[2 -7 5] [-6 2 0]] 2nd Input array: [[0 -7 8] [5 -2 9]] Resul tant output array: [[0 49 40] [-30 -4 0]]
