  # numpy.mod () in Python

Arrays | NumPy | Python Methods and Functions

`numpy.mod()` — this is another function for performing math operations in numpy. It returns the element-wise remainder of the division between the two arrays arr1 and arr2, that is, ` arr1% arr2 `. Returns 0 when arr2 is 0 and arr1 and arr2 are equal (arrays) integers.

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

Parameters :
arr1: [array_like] Dividend array.
arr2: [array_like] Divisor 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] The element-wise remainder ie arr1% arr2.

Code # 1:

 ` # Python program explaining ` ` # numpy.mod () function ` ` `  ` import ` ` numpy as geek ` ` in_num1 ` ` = 6 `` in_num2 = 4   print ( "Dividend:" , in_num1) `` print (` ` "Divisor:" ` `, in_num2) `   ` out_num ` ` = ` ` geek.mod (in_num1, in_num2) ` ` print ` ` (` ` "Remainder:" ` `, out_num) `

Output:

` Dividend: 6 Divisor: 4 Remainder: 2 `

Code # 2:

 ` # Python program explaining ` ` # numpy.mod () function `   ` import ` ` numpy as geek `   ` in_arr1 ` ` = ` ` geek.array ([` ` 2 ` `, ` ` - ` ` 4 ` `, ` ` 7 ` `]) ` ` in_arr2 ` ` = ` ` geek.array ([` ` 2 ` `, ` ` 3 ` `, ` ` 4 ` `]) `   ` print ` ` (` ` "Dividend array:" ` `, in_arr1) ` ` print ` ` (` ` "Divisor array:" ` `, in_arr2) `      ` out_arr ` ` = ` ` geek.mod (in_arr1, in_arr2) ` ` print ` ` (` ` "Output remainder array:" ` `, out_arr) `

Output:

` Dividend array: [2 -4 7] Divisor array: [2 3 4] Output remainder array: [0 2 3] `
