Python Dictionaries and List Comprehensions

Today’s topics

• Dictionaries
• Tuples
• Lists and list comprehensions

🐍 Code Break

• Try working with lists

• Practice with list comprehensions

🎯 Project

Continue yesterday’s project, Word Frequency. A dictionary will help you solve the problem of counting words.

At minimum you should be able to count words and print that count, even if the formatting of your output is not 100% on point.

Working groups for tonight

Don’t struggle through code by yourself! Work together with these folks so you can get to the finish line with Word Frequency.

groups = [
  ['Sara', 'Dee', 'Roan'],
  ['Greg', 'Brian', 'Emily'],
  ['Shaune', 'Wendy', 'Robert'],
  ['Logan', 'Quinten', 'Ellie'],
]
