Anything can be a list

• Comma separated values
• In square brackets
• Can be any value, and a mix of values: Integer, Float, Boolean, None, String, List, Dictionary, ...
• But usually they are of the same type:
• Distances of astronomical objects
• Chemical Formulas
• Filenames
• Names of devices
• Objects describing attributes of a network device.
• Actions to do on your data.
