Sorting list with strings & ints in numerical order

I'm currently dealing with the below list: 

[['John', '1', '2', '3'], ['Doe', '1', '2', '3']]

I'm incredibly new to python, I'm wanting to order this list in numerical order (high - low) but maintain the string at the beginning of the list. Like this:- 

[['John', '3', '2', '1'], ['Doe', '3', '2', '1']]

There will always be one name & integers there after.

I collect this list from a csv file like so:- 

import csv

with open('myCSV.csv', 'r') as f:
    reader = csv.reader(f)
    your_list = list(reader)

print(sorted(your_list))

Any help is much appreciated. Thanks in advance..

Iterate over the list and sort only the slice of each sublist without the first item. To sort strings as numbers pass key=int to sorted. Use reverse=True since you need a reversed order:

>>> l = [['John', '1', '2', '3'], ['Doe', '1', '2', '3']]
>>>
>>> [[sublist[0]] + sorted(sublist[1:], key=int, reverse=True) for sublist in l]
[['John', '3', '2', '1'], ['Doe', '3', '2', '1']]
