Reverse the order of elements in an array along the given axis. The shape of the array is preserved, but the elements are reordered.把数组m在axis维度进行切片,并把这个维度的index进行颠倒示例 随机生成一个二维数组import numpy as np a=np.random.randint(1,9,size=9).reshape((3,3)) ...
arr = np.array([1,2,3,4,5])print(np.flip(arr))# 输出: [5 4 3 2 1]
axis(Optional) – The axis or axes along which elements should be flipped. Ifaxisis not specified or is set toNone, the array is flattened before flipping. Ifaxisis an integer, it specifies the axis to flip. Ifaxisis a tuple of integers, multiple axes can be flipped. 2.2 Return Value ...
