Python | Numpy numpy.ndarray.__ne__() Last Updated : 05 Mar, 2019 Comments Improve Suggest changes Like Article Like Report With the help of numpy.ndarray.__ne__() method of Numpy, We can find that which element in an array is not equal to the value which is provided in the parameter. It will return you numpy array with boolean type having only values True and False. Syntax: ndarray.__ne__($self, value, /) Return: self!=value Example #1 : In this example we can see that after applying numpy.__ne__(), we get the simple boolean array that can tell us which element in an array is not equal to that of provided parameter. Python3 1== # import the important module in python import numpy as np # make an array with numpy gfg = np.array([1, 2, 3, 4, 5, 6]) # applying numpy.__ne__() method print(gfg.__ne__(4)) Output: [ True True True False True True] Example #2 : Python3 1== # import the important module in python import numpy as np # make an array with numpy gfg = np.array([[1, 2, 3, 4, 5, 6], [6, 5, 4, 3, 2, 1]]) # applying numpy.__ne__() method print(gfg.__ne__(4)) Output: [[ True True True False True True] [ True True False True True True]] Comment More infoAdvertise with us Next Article Python | Numpy numpy.ndarray.__ne__() J Jitender_1998 Follow Improve Article Tags : Python Python-numpy Python numpy-ndarray Practice Tags : python Similar Reads Python | Numpy numpy.ndarray.__neg__() With the help of numpy.ndarray.__neg__() method of Numpy, one can multiply each and every element of an array with -1. Hence, the resultant array having values like positive values becomes negative and negative values become positive. Syntax: ndarray.__neg__($self, /) Return: -self Example #1 : In t 1 min read Python | Numpy numpy.ndarray.__sub__() With the help of Numpy numpy.ndarray.__sub__(), We can subtract a particular value that is provided as a parameter in the ndarray.__sub__() method. Value will be subtracted to each and every element in a numpy array. Syntax: ndarray.__sub__($self, value, /) Return: self-value Example #1 : In this ex 1 min read Python | Numpy numpy.ndarray.__and__() With the help of Numpy numpy.ndarray.__and__() method, we can get the elements that is anded by the value that is provided as a parameter in numpy.ndarray.__and__() method. Syntax: ndarray.__and__($self, value, /) Return: self&value Example #1 : In this example we can see that every element is a 1 min read Python | Numpy numpy.ndarray.__isub__() With the help of numpy.ndarray.__isub__() method, we can subtract a particular value that is provided as a parameter in the ndarray.__isub__() method. Value will be subtracted to every element in a numpy array. Syntax: ndarray.__isub__($self, value, /) Return: self-=value Example #1 : In this exampl 1 min read Python | Numpy numpy.ndarray.__invert__() With the help of Numpy numpy.ndarray.__invert__(), one can invert the elements of an array. We don't have to provide any type of parameter but remember that this method only works for integer values. Syntax: ndarray.__invert__($self, /) Return: ~self Example #1 : In this example we can see that ever 1 min read Like
