• Slicing to access ranges of elements
• LHS slice and the RHS may each be of any length
• Slicing Shorthand
• The first is inclusive, and the second is exclusive
• Slice more than what you have
• Slice from the end
• If the slice continues to the end of the sequence, you may simply leave out the last index
• If the slice continues to the start of the sequence, you may simply leave out the first index
• copy the entire sequence, you may leave out both indices
• Another parameter, which normally is left implicit, is the step length
• A step size of two will include only every other element of the interval between the start and the end
• Negative step size
• Slicing a List
• End slice
• Middle slice
• Negative Indices
• Revese and skip
• The starting and ending indices can exceed the length of the string.
