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. After ...
To get the index of the maximum element in a list, we will first find the maximum element with themax()function and find its index with theindex()function. Example: lst=[1,4,8,9,-1]m=max(lst)print(lst.index(m)) Output:
13. 方法2:通过index,max函数获取 deffind_max_index(lst):max_value=max(lst)# 找到列表中的最大值max_index=lst.index(max_value)# 找到最大值的索引returnmax_index# 示例my_list=[3,1,4,1,5,9,2]index_of_max=find_max_index(my_list)print(f"最大值的索引是:{index_of_max}") 1. 2. ...
