# numpy string operations | equal() function

• Last Updated : 26 Jan, 2019

`numpy.core.defchararray.equal(arr1, arr2)` is another function for doing string operations in numpy. It checks the elements of two same-shaped array one by one and returns True if they are equal. Otherwise, it returns False.

Parameters:
arr1 : array_like of str or unicode.
arr2 : array_like of str or unicode.

Returns : [ndarray] Output array of bools, or a single bool if arr1 and arr2 are scalars.

Code #1 :

 `# Python program explaining``# numpy.char.equal() method `` ` `# importing numpy ``import` `numpy as geek`` ` `# input arrays  ``in_arr1 ``=` `geek.array(``'numpy'``)``print` `(``"1st Input array : "``, in_arr1)`` ` `in_arr2 ``=` `geek.array(``'numpy'``)``print` `(``"2nd Input array : "``, in_arr2)  `` ` `# checking if they are equal``out_arr ``=` `geek.char.equal(in_arr1, in_arr2)``print` `(``"Output array: "``, out_arr) `
Output:

```1st Input array :  numpy
2nd Input array :  numpy
Output array:  True
```

Code #2 :

Output:
```1st Input array :  ['Geeks' 'for' 'Geeks']
2nd Input array :  ['Geek' 'for' 'Geek']
Output array:  [False  True False]
```

Code #3 :

 `# Python program explaining``# numpy.char.equal() method `` ` `# importing numpy ``import` `numpy as geek`` ` `# input arrays  ``in_arr1 ``=` `geek.array([``'10'``, ``'11'``, ``'12'``])``print` `(``"1st Input array : "``, in_arr1) `` ` `in_arr2 ``=` `geek.array([``'10'``, ``'11'``, ``'121'``])``print` `(``"2nd Input array : "``, in_arr2) `` ` ` ` `# checking if they are equal``out_arr ``=` `geek.char.equal(in_arr1, in_arr2)``print` `(``"Output array: "``, out_arr) `
Output:

2nd Input array :  ['10' '11' '121']
Output array:  [ True  True False]
