Wordplay Challenges

Check out the Wordplay project which was developed for a different version of this course, and complete as many of the following as you can.

1. Find all words that start with 'a' and are 9 or more letters long.
2. What is the longest word that starts with a 'q'?
3. Find all words that end with 'nge'
4. Find a word that matches "a*ey" (here "*" means any letter). Are there any words that match?
5. Print every other word that matches the condition in (1) above.
6. Find at least one word that uses all five vowels in order.
7. 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

1. (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
