Description
1. Scrabbletm – File, Loop and Dictionary Practice
Write a program that reads a list of words and calculates the Scrabbletmpoint 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
1030Project0401Words.txt
which is included with this specification. Convert lower case letters to upper casewith 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 fromThe 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
1030Project0402Sentences.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)0402Output.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 fromThe 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 1030Project0403Files.txtwhich itself is a list of files
2. Read each of the files, writing them to output file
FirstnameLastname(Your section # here)0403Output.txt
For example, say input file 1030 Project 04 03 Files.txt has these three lines:
1030Project0403File1.txt
1030Project0403File2.txt
1030Project0403File3.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)0403Output.txt, would look like this:
Line 1
Line 2
Line 3
Line 4
Line 5
Line 6
This problem is derived fromThe Python Workbook, by Ben Stephenson, page 70, exercise 143.
What and how to submit
You have nowcreated thesefiles:
FirstnameLastname(Your section # here)0401.py
FirstnameLastname(Your section # here)0402.py
FirstnameLastname(Your section # here)0402Output.txt
FirstnameLastname(Your section # here)0403.py
FirstnameLastname(Your section # here)0403Output.txt
Note you do not submit the input files. If your IDE supports it, turn on line numbering before printing.Submit your programsand accompanying files together in the order shown above. You will lose points if you don’t follow this submission guide.
How your programs are evaluated
1. Do they work according to the specifications?
2. Are the input files and prompts correct?
3. Are the programs documented?
4. Do the programs follow Pythonand file namingstandards?
