print("最小值:", min_val) ```相关知识点: 试题来源: 解析 解析:该程序定义了一个函数`find_max_min`,接受一个列表作为参数,并返回列表中的最大值和最小值。通过遍历列表,不断更新最大值和最小值的变量,最后返回它们的值。最后,输出最大值和最小值。反馈 收藏 ...
根据题干的条件,执行代码s.find("Y"),其中s="Python"。 在字符串"Python"中查找字符"Y",我们可以看到该字符位于索引位置1。 根据字符串的find()方法的返回值规则,如果找到了子字符串,则返回其索引值。因此,执行s.find("Y")应该返回1。 所以,答案为D. 1。通过执行代码并根据字符串的find()方法...
Factors of 2025: Unless you were born before the end of 1936, 2025 will be the only year in your lifetime with exactly 15 factors. 2025 is a composite number. Prime factorization: 2025 = 3 × 3 × 3 × 3 × 5 × 5, which can be written 1458 = 3⁴ × 5². Since its prim...

给定一个整数数组,请编写一个函数,找出数组中第二大的数。如果数组长度小于2,则返回-1。```pythondef find_second_max(nums):if len(nums) first_max:second_max = first_maxfirst_max = numelif num > second_max and num != first_max:second_max = numreturn second_max
```pythondef find_max(numbers): if not numbers: raise ValueError("传入的列表不能为空") max_num = numbers[0] for num in numbers: if num > max_num: max_num = num return max_num``` 原代码的问题在于当传入的numbers为空列表时,会触发IndexError异常(尝试访问numbers[0])。改进方案添加了...
