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
2. Find the Maximum Value of List Using max() Function You can use themax()function to find the maximum value in a list. It takes an iterable(such as list,string,tuple, or,set) as its argument and returns the largest element from that iterable. For example, first, initialize a list ...
Bothsetandfrozensetsupport set to set comparisons. Two sets are equal if and only if every element of each set is contained in the other (each is a subset of the other). A set is less than another set if and only if the first set is a proper subset of the second set (is a subse...
max_val, min_val = find_max_min(lst) print("最大值:", max_val) 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。
Find the Index of Max Value in a List Using for Loop in Python To find the index of max value in a list using for loop, we will use the following procedure. First, we will initialize a variablemax_indexto 0 assuming that the first element is the maximum element of the list. ...
print(str.find("Python",12)) 1. 2. 因为我们从第12个字符开始,所以找不到 Python 这个单词,所以它会返回 -1。 获取子字符串 所以我们得到了我们要搜索的字符串的索引,现在我们要打印匹配的字符串。 你可以按索输出印字符串,如下所示: str = "first second third" ...
Write a Python function that finds the maximum of three numbers without using the built-in max() function by using if-else statements. Write a Python function that accepts three numbers in a list and uses recursion to determine the maximum value. ...
In the second example, we have a list namedCthat contains a combination of numbers and strings. We want to find the mode of this list, which is the element with the highest frequency. To do this, we first create a set from the listCto eliminate duplicates, and then we apply themax(...
Python provides two handy functions,max()andmin(), that makes it easy to find the largest (or the smallest) item in any iterable (e.g. list, set or array) of comparable elements. In this beginner-friendly guide, we’ll explore how to usemax()andmin()effectively. ...
In Python, we can perform the task in multiple ways using one of the multiple methods that are present in the function.Method 1: A way to find the solution is by using list comprehension and to find the maximum values out of all elements of the array, we will use the max() method....
