5.1 Introduction

• Collections are prepackaged data structures consisting of related data items.
• Examples of collections:
  • Favorite songs on your smartphone
  • Contacts list
  • A library’s books
  • Cards in a card game
  • Favorite sports team’s players
  • Stocks in an investment portfolio
  • Patients in a cancer study
  • Shopping list.
• Lists (which are modifiable) and tuples (which are not) have many common capabilities.
• Each can hold items of the same or different types.
• Lists can dynamically resize as necessary.
• The Intro to Data Science section uses the visualization libraries Seaborn and Matplotlib to interactively develop static bar charts containing the die frequencies.
