Using this operation, you can delete any element residing at a specified index. You can remove any element using the built-in remove() method. Example: Python 1 2 3 4 5 6 from array import * array_1 = array('i', [1,2,3,4,5]) array_1.remove(2) for x in array_1: print ...

一、函数np.delete(array,obj,axis)二、函数的意思array:需要处理的矩阵obj:需要处理的位置,比如要删除的第一行或者第一行和第二行axis:如果输入为None:array会先按行展开,然后按照obj,删除第obj-1(从0开始)位置的数,返回一个行矩阵。如果输入为0:按行删除如果输入为1:按列删除import numpy as np x=np.ar...

a = np.array([10, 20, 30, 40, 50, 60, 70, 80, 90, 100]) Now to remove an element at index 3, we use the following code: index = 3 a = np.delete(a, index) delete() is a static method declared in the numpy module. It accepts the array and the index of the element...
