Problem Set 5
CIS 166 & CMP 230, Introductory Programming
Lehman College, City University of New York
Fall 2012

Due Date: midnight, Friday, 12 October.

This assignment focuses on strings and files from Chapter 5.

Submit the following programs via Blackboard:

1. Modify the month.py program from the book (in the Chapter 5 directory of the book's zip file) to print out the full name of each month.
   (Hint: add extra spaces to the months string so that every month's name takes up the same number of characters.)
2. Write a program that asks the user for a sentence and prints the number of characters the user entered.
3. Write a program that asks the user for a word and returns the score of the word, following the scoring rules from the game scrabble. For example:

   		Please enter a word:  quail
   		Your score is 14.
   	

   Scrabble gives most common letters a score of 1 and less common ones higher values (A=1 , B=3, C=3, D=2, E=1, F=4, G=2, H=4, I=1, J=8, K=5, L=1, M=3, N=1, O=1, P=3, Q=10, R=1, S=1, T=1,U=1, V=4, W=4, X=8, Y=4, and Z=10 Scrabble letter distributions).

   So, the word quail above, has a score of 10+1+1+1+1= 14

4. Write a program that asks the user for the name of a file and prints the number of commas (i.e. ,) in the file.
5. Write that asks the user for a file name. You may assume that the file has the following format:

   		12.3 10
   		99 84.3
   		0.3 20
   	

   (two numbers per line). Your program should use a graphics window to display the information in the file. In particular, your program should read each line from the file and display a point at the coordinates indicated. If the first line is 12.3 10 should draw a small circle at (12.3, 10) on the graphics window.

   You may assume that all points have coordinates between 0 and 100 and set the coordinates of the window to be bounded by 0 and 100 in both directions.

   Note that the file could have any number of lines in it.
