Description

Assignment Overview

This assignment focuses on the design, implementation and testing of a Python program which uses file processing, lists and strings to solve the problem described below.

Assignment Specifications

The New York Times newspaper has published “best seller” lists since 1942. Book sales are tracked nationwide, leading to a list of those books that have recently sold the most copies.

You will design, implement and test a program which allows the user to search a subset of the books which have appeared in the New York Times best seller lists. For simplicity, the data set will only contain those books that have reached #1 on either of two lists (fiction and nonfiction) since 1942.

The file named bestsellers.txt contains the data set. Each line of the file contains the information for a separate book, which includes: title, author, publisher, date it first reached #1 on one of the best seller lists, and category (fiction or nonfiction). There is a tab character between fields.

The program will input the data set and construct a list of books. If the list of books cannot be constructed, the program will display an appropriate error message and halt.

After constructing the list of books, the program will display a menu of options and allow the user to search for books that meet certain criteria. The menu options are:

1. Display all books in a year range: Prompt the user for two years (a starting year and an ending year), then display all books that reached the #1 spot between those two years (inclusive). For example, if the user entered “1970” and “1973”, display all books which reached #1 in 1970, 1971, 1972 or 1973.

2. Display all books in a specific month and year: Prompt the user to enter a month and year, then display all books that reached #1 during that month. For example, if the user entered “7” and “1985”, display all books which reached #1 during the month of July in 1985.

3. Search for an author: Prompt the user for a string, then display all books whose author’s name contains that string (regardless of case). For example, if the user enters “ST”, display all books whose author’s name contains (or matches) the string “ST”, “St”, “sT” or “st”.

4. Search for a title: Prompt the user for a string, then display all books whose title contains that

string (regardless of case). For example, if the user enters “secret”, three books are found: “The Secret of Santa Vittoria” by Robert Crichton, “The Secret Pilgrim” by John le Carré, and “Harry Potter and the Chamber of Secrets”.

Assignment Notes

1. Use the starter code. If you need to create additional functions make sure you document your work.

2. You may lists in your program, but you may not use other collections (such as a dictionary or map since we never discussed these yet).

3. Be sure to display the books in a reasonable and readable manner.

4. If no books are found for a particular search, your program will display an appropriate message (rather than simply displaying nothing). For example:

What would you like to do?

1. Look up year range

Enter a title (or part of a title): zombie

The title “zombie” wasn’t found!

5. Your program will continue to execute until the user selects “Q” (or “q”) as the menu option.

5. Be sure to prompt the user for the inputs in the specified order. Also, your program cannot prompt the user for any other inputs.

5. Your program will handle erroneous user inputs. If there are any problems with a particular user input, your program will display the menu and allow the user to select another option.
