How to make a list of string within list in C#

There are a few things diffrent in C# and python but I think you mean something else when you ask for a list. First to handle "Lists" you need to use system generic, like include in python (if I remember correctly) Yes you can have a list of lists and that would look like this,

 List<List<string>> crazyListOfStrings = new List<List<string>>(); 

But I would not suggest that.

This is how you create a list in untiy:

 using System;
 using System.Collections.Generic;
 
 List<string> names = new List<string>();
 //If you wanted to append to the top of the list
 names.add("Tom");
 names.add("Tom2");
 //Now the list contains
 //names[0] == "Tom"
 //names[1] == "Tom2"

But what I think you are looking for is a dictionary and that is almost the exact same way:

 using System;
 using System.Collections.Generic;
 
 class Program
 {
     static void Main()
     {
     Dictionary<string, int> dictionary =
         new Dictionary<string, int>();
 
     dictionary.Add("Tom", 2);
     dictionary.Add("Toms dad", 1);
     dictionary.Add("Toms mom", 0);
     dictionary.Add("Toms kinky boyfriend", -1);
     }
 }
