none of the above Programming questions 11-13 are worth 20 points each
Question 11a (8 points)
Write a function named halfSquare that uses turtle graphics to draw half of a square on the screen. This
involves drawing two lines of equal length, making a 90 degree turn after each. For full credit, these
repeated operations should be performed in a loop.
The function halfSquare takes two parameters
i. t, a turtle that is used for drawing
ii. length, the length of the lines
The function halfSquare should begin drawing without changing the
position or orientation of the turtle t. The turtle t that is passed to
halfSquare may initially be either up or down and may be at any
location on the screen and in any orientation.
The figure at the right shows sample graphical output of halfSquare.
Question 11b (12 points)
Write a function named halfSquares that calls the function halfSquare repeatedly to draw connected
half squares of increasing size. (You can use this technique to draw a spiral pattern.)
The function halfSquares takes four parameters:
i.
ii.
iii.
iv. t, a turtle used for drawing
initial, the length of a side of the first half square
increment, the increase in side length of each successive half square
reps, the number of half squares to draw For example, the graphical output of the code below should
look like the illustration at the right:
import turtle
s = turtle.Screen()
turt = turtle.Turtle()
halfSquares(turt, 20, 20, 10) Question 12 (20 points)
Write a function named wordCount that counts how many words there are in each line of an input file
and writes that count to a corresponding line of an output file. The input file already exists when
wordCount is called. wordCount creates the output file.
Input. The function wordCount takes two parameters:
i. inFile, a string that is the name of a text file that is to be read and analyzed. The file that inFile
refers to contains only upper and lower case letters and white space (no punctuation marks or
other special characters).
ii. outFile, a string that is the name of the file to which wordCount writes its output.
The input file is in the current working directory and you should create the output file to that directory.
Output. For each line of inFile, wordCount should write a corresponding line to outFile containing a
single integer: the number of words on the line.
If the content of the file catInTheHat.txt is below,
The sun did not shine
It was too wet to play
So we sat in the house
All that cold cold wet day
I sat there with Sally
We sat there we two
And I said How I wish
We had something to do
the function call
wordCount('catInTheHat.txt', 'catInTheHatOut.txt') should create a file named catInTheHatOut.txt with this content:
5
6
6
6
5
5
6
5 Question 13 (20 points)
Write a function named initialVowels that analyzes the contents of a text file for words that begin with a
vowel. The letters a, e, i, o and u are vowels.
The function initialVowels should return a dictionary of vowel:word-list pairs. Each vowel should be a
key in the dictionary if and only if it is the first letter of some word in the input file. The value of a key
is a list of all the words in the input file in which that vowel is the first letter. (Hint: your job is easier if
you lowercase the text in the input file.)
Input. The function initialVowels takes a single parameter:
i. inFile, a string that is the name of a text file. This file contains only upper and lower case letters
and white space (no punctuation marks or other special characters). It is in the current working
directory.
Output. Return a vowel:word-list dictionary
For example, if the file named catInTheHat.txt contains the same text as in Question 12, then the
function call
print(initialVowels('catInTheHat.txt')) should output
{'i': ['it', 'in', 'i', 'i', 'i'], 'a': ['all', 'and']}
