Finding the longest and the shortest lists within a list in Python [duplicate]

Question

I need to print the lists which have minimum and maximum number of items in a list.

For example if I have:

total_list = [[1, 2, 3], [1, 2, 3, 4], [1, 2, 3, 4, 5]]

I need to return the lists with a minimum and maximum lengths. How can I do it?

Output could be something like:

total_list[0] and total_list[2]

Answer 1

max and min function in python accepts a key argument that will find the max of an iterable based on what defined as a key. so, try this:

max(total_list, key=len)

then you can use total_list.index to find those indexes
