5.4. Looping with Lists and Dictionaries in Social Media#

We mentioned previously in chapter 4, we can use lists and dictionaries to represent social media data:

Example list of dictionaries of user data

User 1:

  • Username: kylethayer (a String)

  • Twitter handle: @kylemthayer (a String)

  • Profile Picture: (an image)

  • Follows: @SusanNotess, @UW, @UW_iSchool, @ajlunited, … (a list of Strings)

User 2:

  • Username: Dr Susan Notess (a String)

  • Twitter handle: @SusanNotess (a String)

  • Profile Picture: (an image)

  • Follows: @kylemthayer, @histoftech, @j_kalla, @dbroockman, @qaxaawut, @shengokai, @laniwhatison (a list of Strings)

Click to see example Python code

users = [
  {
    username: "kylethayer",
    twitter_handle: "@kylemthayer",
    profile_picture: "kylethayer.jpg",
    follows: ["@SusanNotess", "@UW", "@UW_iSchool", "@ajlunited"]
  },
  {
    username: "Dr Susan Notess",
    twitter_handle: "@SusanNotess",
    profile_picture: "susannotess.jpg",
    follows: ["@kylemthayer", "@histoftech", "@j_kalla", "@dbroockman", "@qaxaawut", "@shengokai", "@laniwhatison"]
  }
]

Now, in order for us to work with this kind of data, we need to look more at lists and dictionaries, as well as how to loop over them.
