How to find the longst element list of lists? I think, there should be an easier way then this: s1 = ["q", "e", "d"] s2 = ["a", "b"] s3 = ["a", "b", "c", "d"] if len(s1) >= len(s2) and len(s1) >= len(s3): sx1=s1 ## s1 ist längster if len(s2...
I have a list the_list = [[3, 2, 0, 1, 4, 5], [4, 2, 1, 3, 0, 5], [0, 1, 2, 3, 4, 5]].How do I print the previous element from any randomly chosen element in the three lists in the_list. If the randomly chosen element is at index 0, then the previous ...
Then incorporates your original solution for find the max element in a list of lists max_value, max_index =max((x, (i, j))fori, rowinenumerate(my_max_list)forj, xinenumerate(row)) For the second problem you can just use the map function ...
如果需要获取列表中的最后一个元素,可以使用负数下标。例如,list_name[-1]可以获取列表中的最后一个元素。 代码示例 下面是一个简单的示例,演示如何通过列表下标查找对应元素: # 创建一个包含5个元素的列表my_list=[10,20,30,40,50]# 获取列表中第3个元素(下标为2)element=my_list[2]print(element)# 输出...
