Chapter 7 - Indexing and Slicing of Sequences

Question 1

Sequence

Answer 1

Compound data type containing one or more pieces of data in a linear order

eg. String

Question 2

Indexing

Answer 2

Operator of a sequence

Logging the position of each character in a sequence

Question 3

Offset

Answer 3

Representation of a characters position in a sequence using an integer

offset = x-1

First position = 0

Use square brackets to access an item using its offset

Negative integers can be used to get the offset from the final character

eg. offset -2 is offset of the second last character

Question 4

Slicing

Answer 4

Selecting zero or more items of a sequence and using them to form a new sequence
