5. Charge Account Validation
If you have downloaded the source code from the Computer Science Portal you will find
a file named charge_accounts.txt in the Chapter 07 folder. This file has a list of a com-
pany's valid charge account numbers. Each account number is a seven-digit number, such
as 5658845.
Programming Exercises 403
program
Write a program that reads the contents of the file into a list. The program should then
ask the user to enter a charge account number. The program should determine whether
the number is valid by searching for it in the list. If the number is in the list, the
should display a message indicating the number is valid. If the number is not in the list, the
program should display a message indicating the number is invalid.

- Program Specification For this assignment you will write a program to help people record the events of their day by supplying prompts and then saving their responses along with the question and the date to a file. Functional Requirements This program must contain the following features: Write a new entry - Show the user a random prompt (from a list that you create), and save their response, the prompt, and the date as an Entry. Display the journal - Iterate through all entries in the journal and display them to the screen. Save the journal to a file - Prompt the user for a filename and then save the current journal (the complete list of entries) to that file location. Load the journal from a file - Prompt the user for a filename and then load the journal (a complete list of entries) from that file. This should replace any entries currently stored the journal.

Your task is to write a program to save a list of students records in a FILE and then perform several operations on this FILE. Your program will ask user to choose the option from a menu. The 3 major function in menu are: ADD STUDENT FIND STUDENT PRINT LIST Exit How it Works The menu is handled by do while and switch statement. Sample output The Methods to be implemented are as follows: 1. ADDSTUDENT This method will add a new student to the file. It takes 3 parameters ( student name, id, and GPA). Your program must ask the user to enter the details of new students: Name, ID and GPA 2. FINDSTUDENT This method will search for a student with his/her id in the file.

You can assume that the input file only one number per line. You can assume the user always enter a file that exists. The median is the value in the middle of a sorted list. To sort a list, use list.sort() function. It’s computed as below. For a list of odd length, the middle number is just the length divide by 2. For the list, [1,2,3], the median is 2 since 2 is in the middle of the list. The middle index is 3//2, which is 1. Remember that // is the integer division operator. When the length of the list is even, there are two middle numbers. The median is the average of the two middle numbers. For example, [1,2,3,4], the median is (2+3)/2 = 2.5. The two middle indexes for this example are (4//2)-1 = 1 and (4//2) = 2.

The user may add more data whenever they want. The print also allows the user to display the data and to print the statistics. The data is store in a list. It’s easier if you make the list global so that other functions can access it. You should have the following functions: · add_from_file() – prompts the user for a file and add the data from it. · add_by_hand() – prompts the user to enter data until user type a negative number. · print_stats() – print the stats (min, max, mean, sum). You may use the built-in functions. Handling errors such as whether the input file exist is extra credit. To print a 10-column table, you can use the code below: for i in range(len(data)): print(f"{data[i]:3}", end="") if (i+1)%10==0: print() print() Sample run: Choose an action 1) add data from a file 2) add data by hand 3) print stats 4)…arrow_forward
