last_element=arr[length-1] 1. 通过使用数组的长度length和索引-1,我们可以获取数组arr的最后一个元素,并将其存储在变量last_element中。 完整代码示例 下面是完整的代码示例,展示了如何实现获取 Python 数组最后一个元素的过程: arr=[1,2,3,4,5]length=len(arr)last_element=arr[length-1]print(last_eleme...

1-D Array Indexing Use bracket notation[ ]to get the value at a specific index.Remember that indexing starts at 0. 1importnumpy as np2a=np.arange(12)3a4#start from index 05a[0]6#the last element7a[-1] Output: array([ 0,1,2,3,4,5,6,7,8,9, 10, 11]) ...
In Python, index -1 means the last element, index -2 means the next-to-last element, etc.代码:class Solution(object): def minMoves2(self, nums): """ :type nums: List[int] :rtype: int """ nums.sort() return sum([nums[~i] - nums[i] for i in range(len(nums) / 2)]) ...
PythonServer Side ProgrammingProgramming In order to remove the first element of the array, the index that must be considered is 0 as the index of the first element in any array is always 0. As like removing the last element from an array, removing the first element from the array can ...
Here, we have to import the array module. Next, we have to create a homogenous linear data structure using the array() and we have stored it in the ‘data’. Now, we have used thepop()that will remove the element from the end or from the last (index value n-1) of the array. ...
