# numpy.divide() in Python

numpy.divide(arr1, arr2, out = None, where = True, casting = ‘same_kind’, order = ‘K’, dtype = None) : Array element from first array is divided by elements from second element (all happens element-wise). Both arr1 and arr2 must have same shape and element in arr2 must not be zero; otherwise it will raise an error. Parameters :
arr1 : [array_like]Input array or object which works as dividend. arr2 : [array_like]Input array or object which works as divisor. out : [ndarray, optional]Output array with same dimensions as Input array, placed with result. **kwargs : allows you to pass keyword variable length of argument to a function. It is used when we want to handle named argument in a function. where : [array_like, optional]True value means to calculate the universal functions(ufunc) at that position, False value means to leave the value in the output alone.
Return :
```An array with arr1/arr2(element-wise) as elements of output array.
```
Code 1 : arr1 divide by arr2 elements
 `# Python program explaining ``# divide() function ``import` `numpy as np `` ` `# input_array ``arr1 ``=` `[``2``, ``27``, ``2``, ``21``, ``23``] ``arr2 ``=` `[``2``, ``3``, ``4``, ``5``, ``6``] ``print` `(``"arr1         : "``, arr1) ``print` `(``"arr2         : "``, arr2) `` ` `# output_array ``out ``=` `np.divide(arr1, arr2) ``print` `(``"\nOutput array : \n"``, out) `

Output :
```arr1         :  [2, 27, 2, 21, 23]
arr2         :  [2, 3, 4, 5, 6]

Output array :
[ 1.          9.          0.5         4.2         3.83333333]
```
Code 2 : elements of arr1 divided by divisor

Output :
```arr1         :  [2, 27, 2, 21, 23]

Output array :
[ 0.66666667  9.          0.66666667  7.          7.66666667]```
Code 3 : warning if arr2 has element = 0
 `# Python program explaining ``# divide() function ``import` `numpy as np `` ` `# input_array ``arr1 ``=` `[``2``, ``27``, ``2``, ``21``, ``23``] ``arr2 ``=` `[``2``, ``3``, ``0``, ``5``, ``6``] ``print` `(``"arr1         : "``, arr1) ``print` `(``"arr2         : "``, arr2) `` ` `# output_array ``out ``=` `np.divide(arr1, arr2) ``print` `(``"\nOutput array : "``, out) `

Output :
```arr1         :  [2, 27, 2, 21, 23]
arr2         :  [2, 3, 0, 5, 6]

Output array :  [ 1.          9.                 inf  4.2         3.83333333]
