array=[1,2,3,4,5]deleted_element=array.pop(2)print(array)# 输出:[1, 2, 4, 5]print(deleted_element)# 输出:3 1. 2. 3. 4. 上述示例中,我们通过array.pop(2)删除了数组array中索引为2的元素,并将被删除的元素值赋给了变量deleted_element。最终输出结果为[1, 2, 4, 5]和3。 方法三:使...
variable = n.delete(arr, first_index) 例 在这个例子中,我们将讨论使用 Numpy 模块的 delete() 方法删除数组的第一个元素的过程。 import numpy as n arr = [" Hello ", " Programming ", " Python ", " World ", " Delete ", " Element "] variable = n.array(arr) first_index = 0 print(...

Given input arraynums=[3,2,2,3],val=3 Your function should return length = 2, with the first two elements ofnumsbeing 2. 给定一个数组和一个数值val,将数组中数值等于val的数去除,返回新数组的长度。不能申请额外空间,超过新数组长度部分忽略。

elements=e.getSequenceFromMask(mask=('[#1 ]', ), )part.deleteElement(elements=elements) 乍一看比较乱,但是看多了就习惯了,练习多了,你就知道里面哪些语句是你需要的。这里主要用的函数是deleteElement(),注意一下这里传入的参数是单元的单元的sequence,有些函数是传入的是element对象,这点很容易搞混淆。
