Intro to Programming and Data Science (Summer 2020)/Day 2 Coding Challenges: Difference between revisions

Revision as of 17:10, 15 May 2020

As a reminder, it's not essential that you solve or get through all of these — 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 but I encourage you to make sure that you understand the concepts yourself.

Required

Finish 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*

(Starred exercises are optional; if you feel like you need more practice in a topic)

The only thing I ask is that you do not broadcast answers on Brightspace more than 24 hours before class.

-== 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
