Suggest a situation where you can use a regular two dimensional list.

What are ragged lists ? How are these different from two dimensional lists ?

How are lists internally stored ? How are 2D lists internally stored ?

Create a list SqLst that stores the doubles of elements of another list NumLst. Following code is trying to achieve this. Will this code work as desired ? What will be stored in SqLst after following code ?

NumLst = [2, 5, 1, 7, 3, 6, 8, 9]
SqLst = NumLst * 2
