Skillup Africa Beneficiary Challenge

Project Brief

Write a Python program that allows customers to:

• Create an account with the account number generated if they do not have an account. All generated account numbers should begin with 0
• Log in to the program if they have an account
• Deposit money
• Withdraw money from the account if they have a sufficient amount.
• Users should be able to transfer money to other users in the account.
• Users should be able to check their account balances.
• The program should keep running until the user decides to make it log out and/or quit.
• The account data should be stored in a dictionary that looks like this:

{
"0123445677" : { 
"first_name":"John", 
"last_name" : "Doe ", 
"login_pin" : "8424",
"transaction_pin" : "0934", 
"balance" : 0 }
}

Install Dependencies

1. Python 3.7 - Follow instructions to install the latest version of python for your platform in the python docs

2. Virtual Environment - We recommend working within a virtual environment whenever using Python for projects. This keeps your dependencies for each project separate and organized. Instructions for setting up a virual environment for your platform can be found in the python docs

Set up Storage for Persistence

The dictionary which contains users details is stored in a .txt file. Navigate to your project folder and create a .txt file containing an empty dictionary.

with open('bank_app_db.txt', 'r') as file:data = eval(file.read()) and

with open('bank_app_db.txt', 'w') as file:file.write(str(data))

for persistence

Documentation

The project makes use of Pythons Data Structures, Algorithms, Methods and makes use of the following functions:

def deposit()

• To deposit money.

def withdraw()

• To withdraw money if user balance is sufficient.

def account_num()

• To generate a random account number starting with '0'
