def sum_of_list(numbers):这是函数的定义。它告诉 Python 你正在创建一个名为 sum_of_list 的函数，并且这个函数需要一个参数 numbers，用于传递列表。total = 0：这一行创建了一个变量 total，并将其初始化为零。这个变量将用于累积列表中的元素总和。for number in numbers:这是一个 for 循环，它遍历列表...
Question 2 Add Two Numbers:You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. You may assume the two numbers do not c...
Given an array of integers, return indices of the two numbers such that they add up to a specific target. You may assume that each input would have exactly one solution, and you may not use the same element twice. classSolution(object):deftwoSum(self, nums, target):""":type nums: Li...

例如，sum(map(lambda x: x * 2, range(1, 5)))将返回20，表示范围1到4中每个元素的两倍之和。在循环中使用：在循环中使用列表求和函数可以方便地计算一系列数字的总和。例如，以下代码可以计算一个列表中所有奇数的总和：numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9] sum_of_odds = sum(x for...
