CS3210-Project 4 Solved

1.   Scrabbletm – File, Loop and Dictionary Practice

 

Write a program that reads a list of words and calculates the Scrabbletm point value of each word. If the word has 0 characters or 10 characters or more, assign a point value of 0. The words are read one per line from file

                  1030 Project 04 01 Words.txt

which is included with this specification. Convert lower case letters to upper case with a statement like

            letter = character.upper()

and ignore all characters that aren’t letters. You can test if a character is a letter with

            if letter.isalpha()

Point values are based on this table which can be conveniently implemented with a dictionary:

 

# points
Letters
1
A, E, I, L, N, O, R, S, T, U
2
D, G
3
B, C, M, P
4
F, H, V, W, Y
5
K
8
J, X
10
Q, Z
 

An actual Scrabbletm board includes some squares that multiply the value of a letter or the value of an entire word. For this problem, ignore these squares. The output should be in a list with the word and its points, with the point total displayed at the end of the program. For example:

 

                                          Word                     Points

                                          CAT                            3

                                          DOG                           5

                                          FOX                           13

                                          HIPPO                       12

                                          PLATYPUS               15

 

                                          Total                          48

 

This problem is derived from The Python Workbook, by Ben Stephenson, page 66, exercise 137.

 

2.   Letter Frequencies – File, Loop and Dictionary Practice

 

Write a program that reads sentences from file

                  1030 Project 04 02 Sentences.txt

 

(included with this specification) and calculates letter frequencies (total counts of how often each letter appears) for all sentences in the file. Print the original lines as you read them. Then, convert lower case letters to upper case and ignore all characters that aren’t letters. Frequency analysis is one approach to decrypting messages. The letters E and T are the most common letters in the English language, so a frequency analysis of a long message would likely show high counts for letters E and T.

 

After processing all lines in the input file, display on the screen and write to output file

                  FirstnameLastname (Your section # here) 04 02 Output.txt

the letters and their frequencies. Here’s an example. Given lines

                  See Spot.

                  See Spot code in Python.

The screen display and output file would look something like:

 

                  Letter   Frequency

                      A             0

                      B             0

                     ….          ….

                      E            5

                     ….          ….

                      O           4

                      P            1

                     ….          ….

                      S            4

                     etc.         etc.

 

 

This problem is derived from The Python Workbook, by Ben Stephenson, page 71 exercise 146.

 

3.   Concatenate Multiple Files – File and List Practice

 

Write a program that concatenates (combines) one or more files, writing them to an output file:

      1.   Reads input file 1030 Project 04 03 Files.txt which itself is a list of files

      2.   Read each of the files, writing them to output file

            FirstnameLastname (Your section # here) 04 03 Output.txt

 

For example, say input file 1030 Project 04 03 Files.txt has these three lines:

            1030 Project 04 03 File 1.txt

            1030 Project 04 03 File 2.txt

            1030 Project 04 03 File 3.txt

The first file has these lines:

            Line 1

            Line 2

The second one has this line:
Line 3

The third file has these lines:

            Line 4

            Line 5

            Line 6

 

 

 

The output file, FirstnameLastname (Your section # here) 04 03 Output.txt, would look like this:

            Line 1

            Line 2

            Line 3

            Line 4

            Line 5

            Line 6
