How to find most frequent list within a list - Python

Question

For example, how would you find the most occurred list within a list of lists and appropriate counts. Counter from collections doesn't seem to accept lists as elements.

my_list = [[10, 2, 14], [1, 4, 6], [2, 3, 4], [10, 2, 14]]
# most frequent list: ([10, 2, 14], 2)

Answer 1

It does not accept mutable elements, but for simple lists you can convert it to tuples:

from collections import Counter

my_list = [[10, 2, 14], [1, 4, 6], [2, 3, 4], [10, 2, 14]]

Counter(tuple(i) for i in my_list).most_common()

you have to convert the most common element back to a list of course.
