How to Find a Simple Interest in Python

Submitted by razormist on Thursday, April 4, 2024 - 23:44.

In this tutorial, we will program 'How to Find Simple Interest in Python'. We will learn how to calculate simple interest in Python. The main goal here is to create a program that will easily calculate the simple interest for your payments. I will provide a sample program to demonstrate the actual coding of this tutorial.

This topic is very easy to understand; just follow the instructions I provide, and you can also do it yourself with ease. The program I will show you covers the basics of programming for calculating simple interest. I will do my best to provide you with the easiest method of finding the simple interest. So, let's start with the coding.

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

def simple_interest(p,t,r):
        print('The principal is', p)
        print('The time period is', t)
        print('The rate of interest is',r)
        
        si = (p * t * r)/100
        
        print('The Simple Interest is', si)
        return si
        
 
 
while True:
        ret = False
         
        print("====================== Find a Simple Interest in Python ====================== \n\n")
 
 
        p = int(input("Enter the principal: "))
        t = int(input("Enter the time period: "))
        r = int(input("Enter the rate of interest: "))
        print("\n")
        
        
        simple_interest(p, t, r)
        print("\n")
 
        opt = input("Do you want to update again?(yes/no): ")
 
        if opt.lower() == 'yes':
                ret=False
        elif opt.lower() == 'no':
                ret=True
                print("Exiting program....")
 
        else:
                print("Please enter yes/no:")
                break
 
        if ret == False:
                continue

This Python code calculates and displays the simple interest based on user-provided values for principal amount, time period, and interest rate. It then prompts the user if they want to update the values and continues looping until the user chooses to exit.
