Functions Quiz

Setup

Open the Python String page.

Fork the repository, then clone your fork.

Disconnect your computer from the internet.

Quiz

Open quiz.py.

Follow this process:

1. Write the code to test a function first!
2. Use the testing code to write the method.
3. Commit with message "Implement method_name"
4. Move on to the next method
5. When all done, verify everything still works and there are no syntax errors.
6. Your quiz must define each function, or the grading software will not work. Check that the function names and their number of arguments match the problem declarations exactly.
7. Turn it in with: $ git push
8. Have a TA run the grading software and record your results.

Functions to Implement

1. has_teen

   A number is a teen if it is in the range 13 to 19 inclusive. Given three integers, return true if any of them are a teen.

2. not_string

   Given a string, return a new string where "not" has been added to the front. However, if the string already begins with "not" add the not to the end instead.

3. icy_hot

   It is icy if a temperature is less than zero, and it is hot if a temperature is greater than 100. Given two temperatures, return true if either one is icy and the other is hot.

4. closer_to

   Given a target number and two guesses, return the guess that is closer to the target. If they are the same distance, return 0.

5. two_as_one

   Given three integers, return true if it is possible to add two of the ints to get the third.

6. pig_latinify

   Given a word, return its pig latin conversion.

   Most words in Pig Latin end in "ay." Use the 2 simple rules below to translate normal English into Pig Latin.

   • If a word starts with consonants move the consonants to the end of the word and add "ay."

   • If a word starts with a vowel add the word "way" at the end of the word.

   Your code should work for as many english words as possible. I will try to break it! It should also handle some problems with user input:

   • Ignore white space around the original input, so it should return "appleway" for both "apple" and " apple ".
   • Ignore case, so it should return "appleway" for both "Apple" and "aPpLe"
   • Extra Credit | If a user types in a curse word pig_latinify should censor the result by replacing any vowel in the original word with an asterisk
