As a reminder, it's not essential that you solve or get through all of these β I'm not grading your answers on these. That said, being able to work through at least many of them is a good sign that you have mastered the concepts for the week. It is always fine to collaborate or work together on these problem sets. The only thing I ask is that you do not broadcast answers on Brightspace more than 24 hours before class. == Required == * Finish [https://www.datacamp.com/courses/intro-to-python-for-data-science DataCamp Intro to Python] Chapter 1 * Python for Everyone Exercises: ** Chapter 1: Exercises 1, 6, 7 ** Chapter 2: Exercises 2, 3, 4, 5 ** Chapter 3: Exercises 1, 2, 3* ** Chapter 4: Exercises 1-4*, 5, 6, 7* (Starred exercises are optional; if you feel like you need more practice in a topic) == Additional Challenges == Check out the [[Wordplay]] project which was developed for a different version of this course (and which we may come back to later). Challenges about finding words: # Find all words that start with 'a' and are 9 or more letters long. # What is the longest word that starts with a 'q'? # Find all words that end with 'nge' # Find a word that matches "a*ey" (here "*" means any letter). Are there any words that match? # Print every other word that matches the condition in (1) above. # Find at least one word that uses all five vowels in order. # For every letter, print the word that uses that character the most. (Hint: use two nested for loops. First one is for letter in 'abcdefghijklmnopqrstuvwxyz': # do something # (Challenge) Find the longest string where no character appears more than 1 time. (Hint: look up counters) Use Python to find one other interesting fact about the data set. Examples (that you can't use) might be: * One of the words that is tied for the most vowels is aquifoliaceous * The word with the highest consonant to vowel ratio is sulphhydryls
