numpy.array_equal(arr1, arr2) : This logical function that checks if two arrays have the same shape and elements.
Parameters :
Python
Output :
arr1 : [array_like]Input array or object whose elements, we need to test. arr2 : [array_like]Input array or object whose elements, we need to test.Return :
True, if both arrays have same shape and value; otherwise FalseCode : Explaining Working
