Need In 10 Hours Maximumtaskin The Resources Section Of The Interact2

Need in 10 Hours Maximum Task in the Resources section of the Interact2 subject website there is a data file called students.txt. This file contains student details: a valid student number, course (BIT or MIT), and the specialisation (ex: software design and development). Each student number is an eight-digit number such as . (Note: Two records in the file have intentionally been "corrupted" - for testing purposes.) Design an algorithm and use it to write a Python program that allows the user to read the contents of the data file into a list. The program should then loop, to allow a user to check various numbers against those stored in the list. The loop should terminate when an "empty" input occurs - i.e., when the user presses the [Enter] key on its own. (Obviously this last entry should NOT be checked against the list!) If the student number input matches an element somewhere in the list, the program should display the number together with the course and the specialisation. If the number input does not match any element in the list, then the program should display the number and a message saying that it IS NOT a valid student number. Notes: The algorithm should be written in pseudocode (structured English). The records read from the data file should be checked and NOT placed into the list if they are something other than an 8-digit number. (Display a sensible message if the file is found to have corrupt records in it.) The numbers entered by the user should be checked to ensure they are valid digits (as distinct from valid student numbers) and not processed further if they are not. Your programs should use one or more functions where sensible, and be documented fully. Use exceptions where necessary. Specify 3 sets of test data that will demonstrate the correct ‘normal’ operation of your program. Show your test data in a table as you have done in earlier assignments. Run your program using the test data you have selected and save the output produced in a single text file. Submit: 1. Your algorithm and test data table. 2. The table recording your chosen test data. 3. Source code for your Python implementation. 4. Output test file demonstrating the results of using the test data. 5. Contents of the data file cars.txt read by the program. It is important that the output listings are not edited in any way. Rationale Reinforce topic material related to files and exceptions. Reinforce topic material related to lists.

Student Data Validation and Lookup Python Program

The task involves designing a Python program that reads student records from a data file, validates the records, stores valid entries in a list, and allows users to check if specific student numbers exist within that list. The program must handle corrupt data records gracefully, validate user inputs, and make use of functions for modularity. This paper provides an algorithm in pseudocode, a demonstration of the testing process with three distinct datasets, the Python code implementation, and sample output results, aligning with the project’s objectives to reinforce knowledge of file handling, exception management, and list operations.

Algorithm in Pseudocode

BEGIN
DECLARE students_list as empty list
TRY
OPEN "students.txt" for reading
READ each line from the file
FOR each line
SPLIT line into student_number, course, specialisation
IF line has exactly three parts
CHECK if student_number is exactly 8 digits and numeric
IF valid
APPEND a tuple (student_number, course, specialisation) to students_list
ELSE
DISPLAY "Corrupt record found, skipping: " + line
ELSE
DISPLAY "Corrupt record found, skipping: " + line
END FOR
CLOSE file
CATCH FileNotFoundError
DISPLAY "Data file not found."
EXIT program
END TRY
REPEAT
PROMPT user for input "Enter student number to search (or press Enter to quit): "
IF input is empty
BREAK the loop
ELSE
IF input is numeric and has exactly 8 digits
SEARCH students_list for matching student_number
IF found
DISPLAY student_number, course, specialisation
ELSE
DISPLAY student_number + " IS NOT a valid student number."
ELSE
DISPLAY "Invalid input. Please enter an 8-digit student number."
UNTIL false
END
