Consider the following class:

  public class Animal
  {
    public string Name { get; set; }
    public int NumberOfLegs { get; set; }
  }

var Animal = { 
    name: "Cat", 
    numberOfLegs: 4 
}

class Animal:
    def __init__(self, name, number_of_legs):
        self.name = name
        self.number_of_legs = number_of_legs

Write a method that accepts a list of objects of type Animal, and returns a new list. The new list should be a copy of the original list, sorted first by the animal's number of legs, and then by its name.

If an empty list is passed in, it should return an empty list back.
