How to rank elements within a 2D array-CodePudding

I have an array of data representing web page traffic that is structured like this, where element 0 of each item is the page name, element 1 is pageviews and element 2 is number of users

[['page 1 name','3678','400']['page 2 name','4000','123']['page 3 name','3802','750']]

How do I go about ranking these items by pageviews and number of users and appending the ranks to the end of the array elements, to end up with

[['page 1 name','3678','400','3','2']['page 2 name','4000','123','1','3']['page 3 name','3802','750','2','1']]

Apologies for not including any code, but I've searched everywhere and can't find any clue about where to start with this.

The simplest logic, sort and append the index to the end

lst = [['page 1 name','3678','400'], ['page 2 name','4000','123'], ['page 3 name','3802','750']]

views_lst = sorted(lst, key=lambda x: int(x[1]), reverse=True)
numbers_lst = sorted(lst, key=lambda x: int(x[2]), reverse=True)
for sorted_item in [views_lst, numbers_lst]:
    lst = [item   [str(sorted_item.index(item[:3])   1)] for item in lst]
print(lst)

OUTPUT:

[['page 1 name', '3678', '400', '3', '2'], ['page 2 name', '4000', '123', '1', '3'], ['page 3 name', '3802', '750', '2', '1']]
