Suppose that we are given a 2D numpy array and we need to find the row index of several values in this array. For example, if we are given an array as: [[1, 2], [3, 4], [5, 6], [7, 8], [9, 10]] And, we need to extract the indices of [1,2], [5,6] and [9...
An array can be indexed by a tuple of nonnegative integers, by booleans, by another array, or by integers. Therankof the array is the number of dimensions. Theshapeof the array is a tuple of integers giving the size of the array along each dimension. 我们可以初始化NumPy数组的一种方法...
4.Find indices of non-zero elements from [1,2,0,0,4,0] (★☆☆) z = [1,2,0,0,4,0] n = np.nonzero(z) print(n) 5.Create a 10x10 array with random values and find the minimum and maximum values (★☆☆) Z = np.random.random((10,10)) ...
Finding the indices list of all NaN value in NumPy array To find the indices list of all NaN value, we will usenumpy.isnan()combined withnumpy.argwhere.isnan()method produces a bool array indicating where the NaN values are. Hence, it returns the nan value andnumpy.argwhere()returns t...
numpy.unique(ar, return_index=False, return_inverse=False,return_counts=False, axis=None) Find the unique elements of an array. 查找数组的唯一元素。 return_index:the indices of the input array that give the unique values return_inverse:the indices of the unique array that reconstruct the inpu...

numpy.argsort(a[, axis=-1, kind='quicksort', order=None]) Returns the indices that would sort an array. 【例】对数组沿给定轴执行间接排序,并使用指定排序类型返回数据的索引数组。这个索引数组用于构造排序后的数组。 importnumpyasnp np.random.seed(20200612) ...
