当你定义一个函数 sum_of_list(numbers) 时，你实际上创建了一个可以在其他部分的代码中重复使用的功能块。这个函数的目的是计算给定列表 numbers 中所有元素的总和。现在，我会详细解释这段代码的每一部分：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，...

递归情况意味着总和是第一个值numbers[0],加上其余值的总和numbers[1:]。由于递归情况在每次迭代中使用较短的序列,因此您希望在numbers是零长度列表时遇到基本情况。作为最终结果,您将获得输入列表中所有项目的总和numbers。 注意:在此示例中,如果您不检查空输入列表(您的基本情况),则sum_numbers()永远不会遇到无限...
Given an array of integers, returnindicesof the two numbers such that they add up to a specific target. You may assume that each input would haveexactlyone solution, and you may not use thesameelement twice. Example: Given nums = [2, 7, 11, 15], target = 9, because nums[0] + nu...
