Question
Hello! This is a python program I need help with.
You are going to write a program called BankApp to simulate a banking application.
The information needed for this project are stored in a text file. Those are:
usernames, passwords, and balances.
Your program should read username, passwords, and balances for each customer, and
store them into three lists.
userName (string), passWord(string), balances(float)
The txt file with information is provided as UserInformtion.txt
Example: This will demonstrate if file only contains information of 3 customers. You
could add more users into the file.
userName passWord Balance

When a user runs your program, it should ask for the username and password
first. Check if the user matches a customer in the bank with the information
provided. Remember username and password should be case sensitive.
After asking for the user name, and password display a menu with the following
options and ask the user for input (Use a While Loop).
Type D to deposit money
Type W to withdraw money
Type B to display Balance
Type C to change user, display user name
Type A to add new client
Type E to exit
If the user types D
(Deposit Function) Ask the user to enter the amount to deposit.
Then call the Deposit Function, passing the deposit amount as a parameter. The
function should update the Balance.
Then display the new balance (this should happen by calling the ShowBalance
function).
Then display the menu again
If the user types W
(Withdraw Function) Ask the user to enter the amount he/she wants to withdraw.
Before calling the withdraw function, make sure there is enough balance. Call
the ShowBalance function before Withdraw function!!
Then call the Withdraw Function, passing the withdraw amount as a parameter.
The function should update the Balance.
Display the new balance to the user.
Then display the menu again
If the user enters B
(ShowBalance Function)
Display the Balance.
If the user enters C
(ChangeUser Function) Ask for the user name and change to a different
customer.
If the user enters A (AddNewUser function) Ask for username, password,
and balance. These information will be added to the appropriate lists which
later on will be transfered to the UserInformation.txt
If the user types any other option: Prompt the user that option is invalid
If the user types E then
Terminate the program and update the UserInformtion.txt with the correct
updated balances.
PS: You program must keep displaying the menu until the user types the option
E, to exit the program.

- HELLO. I NEED HELP WITH THIS PROBLEM FROM STARTING OUT WITH VISUAL C#, 5TH EDTION BY TONDY GADDIS. THIS IS FROM CHAPTER 13, PROGRAMMING PROBLEM #4. English Surnames In the student sample program files for this chapter, you will find a text file named surnames.txt. The file contains 14,674 English surnames. Each line in the file has one surname. Write a program that reads the names from the file into a List. The program should let the user perform the following searches: Find all the names that are longer than a specified length. Find all the names that are shorter than a specified length. Find all the names that begin with a specified string of characters. (For example, find all the names that begin with “All”.) Determine whether a specified name exists in the List.arrow_forwardYou are working with a team creating a grocery shopping app. The app keeps the information of the items to buy in the list grocery list, and the items that were purchased in purchased list. You need to create a function that returns the items that were purchased, but that were not in the grocery list. For example, if the grocery list is milk, eggs, bacon, and flour; and we purchased milk, chocolate, and muffins, the function should return a list with chocolate and muffins. Drag and drop the expressions needed to implement the required function. def get_extra_items(grocery_list, purchased_list): list3 [] for i in range( ) : if not in list3.append( return list3 len(grocery_list) grocery_list grocery_list[i] purchased_list[i] purchased_list len(purchased_list)arrow_forwardPROBLEM 1: Have you ever wondered how websites validate your credit card number when you shop online? They do not check a large database of numbers. Most credit providers rely on a checksum formula for distinguishing valid numbers from random collections of digits (or typing mistakes). The objective of this lab you will implement a program that read a file that contains a table with two columns: A column of customer names and a column of credit card numbers. For each customer, print the validity of the credit card number and name of the corresponding credit card company (if the number is valid), For our purpose, the algorithm that valid credit cards is the following: Double the value of every second digit beginning from the right. That is, the last digit is unchanged; the second-to-last digit is doubled; the third-to-last digit is unchanged; and so on. For example, [1,3,8,6] becomes [2,3,16,6] Add the digits of the doubled values and the undoubled digits from the original number. For…arrow_forward
- Write a Python program that creates a List called MonthsOfTheYear. The program should display the name of the months with 31 days only.arrow_forwardWrite in JAVA When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow. Assume that the list will always contain fewer than 20 floating-point values. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("%.2f", yourValue);arrow_forwardthe volume of traded Apple stocks during February and March 2022.

In addition, the program must display the whole trade volume, average trade volume for each month and shows the month that Apple has a higher trading volume.Sample Output:___________ has the maximum trade volume of ______________ in February.___________ has the minimum trade volume of ______________ in February.___________ has the maximum trade volume of _____________ in March.___________ has the minimum trade volume of ______________in March.The whole trade volume of these two months is ______________.The average trade volume of February is ______________.The average trade volume of March is ______________.AAPL has higher trading volume in…arrow_forward
- Python programming only NEED HELP PLEASEarrow_forwardThis task involves writing a program that calculates the standard deviation of all numbers in a list. First, the number of the number in the list is entered, then each number is entered. The program should print the standard deviation of the numbers in the list. Note, the values entered into the program are part of a random sample, which may need to be taken into account when choosing a method to calculate the standard deviation.arrow_forwardPython code.

- Needs to use python and methodsarrow_forwardOne of the things discussed in this chapter is the sorting of data. Imagine that a large medical center hires you to write a program that displays a list of potential organ recipients. The hospital's transplant team will consult this list if they have an organ available for transplant. The hospital administrators have instructed you to sort potential recipients by last name and display them in alphabetical order. If more than 10 patients are waiting for a particular organ, the first 10 patients will be displayed; a doctor can either select one or move on to view the next 10 patients. You are concerned that this program will unfairly select patients whose last names begin near the front of the alphabet. It's critical that the hospital has a program written quickly, as the hospital currently has no method of going through potential organ recipients. Based on this, answer the following questions in detail: Would you write and install the program? If yes, would you change anything about…arrow_forwardPlease help me with this in python.
