In the below example, we have used numpy.arange() method to create an array within the specified range of values. Example: import numpy as np x = np.arange(3) print("Array x : ", x) y = np.arange(10,15) print("\nArray y : ", y) res = np.append(x, y) print("\nResult...

A copy of "arr" with "values” appended to `axis`. Note that `append` does not occur in-place: a new array is allocated and filled. If `axis` is None, `out` is a flattened array. 带有"values"的"arr"的副本附加到"axis"。注意,"append"并不是就地发生的:一个新的数组被分配和填充。
