```pythondef sum_of_evens(numbers): return sum(num for num in numbers if num % 2 == 0)``` 解决该问题的步骤如下:1. **问题分析**:需要计算一个整数列表中所有偶数的和。核心步骤是过滤偶数,然后求和。2. **判断条件**:判断一个数是否为偶数可通过 `num % 2 == 0` 实现。3. **遍历列...
在这种情况下,无论您的数字列表是长列表还是短列表,Python 在解决求和问题方面都非常有用。 如果您想通过从头开始创建自己的解决方案来对数字求和,那么您可以尝试使用for循环: >>> >>> numbers = [1, 2, 3, 4, 5] >>> total = 0 >>> for number in numbers: ... total += number ... >>> to...
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...

Python List Exercises, Practice and Solution: Write a Python program to calculate the sum of the numbers in a list between the indices of a specified range.
编写一个Python函数,接收一个整数列表作为参数,返回列表中所有偶数的平均值。 ```python def average_even(numbers): evens = [x for x in numbers if x % 2 == 0] if len(evens) == 0: return 0 return sum(evens) / len(evens) numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10...
四、应用题题目:编写一个简单的Python程序,计算给定列表中所有元素的和。```pythonnumbers = [1, 2, 3, 4, 5]sum = 0for num in numbers:sum += numprint("列表元素的和为:", sum)``` 相关知识点: 试题来源: 解析 答案:列表元素的和为: 15 ...
