def sum_even_numbers(numbers): return sum(num for num in numbers if num % 2 == 0) 1. **问题分析**:函数需要计算列表中所有偶数的和。偶数的定义为能被2整除(即余数为0),遍历列表中的每个元素进行判断即可。2. **方案设计**: - 初始化总和为0。 - 遍历列表中的每个元素。 - 对每个元素检查...
题目:请写出一个Python函数,该函数接收一个整数列表作为参数,并返回列表中所有偶数的和。 ```python def sum_even_numbers(numbers): return sum(num for num in numbers if num % 2 == 0) ```相关知识点: 试题来源: 解析 答案:函数`sum_even_numbers`通过列表推导式筛选出列表中的偶数,并使用内置函数`...
Problem: How can you sum a list of strings such as ['python', 'is', 'great']? This is called string concatenation. Solution: Use the join() method of Python strings to concatenate all strings in a list. The sum() function works only on numerical input data. ...
