A variable can hold multiple values in the form of a list. The values are separated by commas

and wrapped in square brackets. For example:

primes $=[2,3,5,7,11,13,17,19,23,29]$

Each element of the list can be referenced by an index, which is the sequential position starting

at $0.$ For example, primes$[4]$ is $11.$

index $0123456789$

value $2357111317192329$
