This repo shows a simple Python program for modeling the potential earned interest for a savings account and for a CD.
The project presents a potential solution for the UNC-Chapel Hill AI bootcamp assignment for the Module 3 Challenge.
At the Command Line: Run python3 customer_banking.py
The program will prompt you to enter values for the current balances for a hypothetical savings and CD account, the APRs for their interest, and the number of months to calculate the new balance.
The program's primary class outlines the core functions of a customer's account.
- Parameters:
balance
andinterest
- Methods
set_balance
: Float. Sets the balance for the account.set_interest
: Float. Sets the interest rate for the account.
This file defines the reate_cd_account
function and includes methods for calculating the potential earned interest for a CD.
- Parameters:
balance (float)
,interest_rate (float)
,months (float)
- Returns:
cd_balance (float)
: The updated CD account balance after adding the interest earned.cd_interest_earned (float)
: The interest earned.cd_months (int)
: The number of months used to calculate the new balance.
This file defines the create_savings_account
function, which includes methods for calculating the potential earned interest for a savings account.
- Parameters:
balance (float)
,interest_rate (float)
,months (float)
- Returns
savings_balance (float)
: The updated savings account balance after adding the interest earned.interest_earned (float)
: The earned interest.savings_months (int)
: The number of months used to calculate the savings_balance.
This file executes the program and includes three functions:
get_float_input
takes in two parameters: the user's input as a float and the minimum value that the input should accept. This ensures users cannot enter 0, a negative number, or a character.get_int_input
takes in two parameters: the user's input as an int and the minimum value that the input should accept. This ensures users cannot enter 0, a negative number, or a character.- The
main
function includes code to prompt the user to input values to calculate the potential earned interest and final balances for a savings account and a CD. The inputs call theget_float_input
andget_int_input
functions, passing theprompt
input text and themin_value
arguments.
While entering 0 is technically permitted, the program makes no sense if we don't require a value greater than 0. We're calculating interest.
Note I chatted with Copilot to learn how to add input validation to my inputs and added this to my code after further study.
