Sequence Slicing

When we provide a slice to any sequence object (object that implements __getitem__ and __len__), we get back an instance of the same type with the elements in the slice. Here is how slicing works:

• When we have commas inside [], __getitem__ gets tuple of slice object.
• When we have : inside [], __getitem__ gets a slice object.

slice object has 4 important attributes:

• start
• step
• stop
• indices
