Python: How do I find the list with the most elements in it

Question

Using Python I want to output the name of the list with the most elements in it.

List1 [1,2,4,5,7,2]
List2 [1,4,5,6]
List3 [2,5,4,6,7,8,5,3,]

Answer 1

you can use numpy:

import numpy as np

list1 = [1,2,4,5,7,6,5]
list2 = [1,4,5,6]
list3 = [2,5,4,6,7,8,5,3]

lists=[list1, list2, list3]
listsnames=["list1", "list2", "list3"]

most= listsnames[np.argmax([len(l) for l in lists])]
