In this tutorial, we will program 'How to Calculate Compound Interest in Python'. We will learn how to calculate compound interest based on user input. The objective is to allow you to calculate your total compound interest using the principal amount, years, and interest rate. 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 compound interest. I will do my best to provide you with the easiest way for getting the interest value. 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 compound_interest(principal, rate, time):

Amount = principal * (pow((1 + rate / 100), time))

CI = Amount - principal

print("Compound interest is", CI)

ret = False

while True:

print("\n================== Calculate Compound Interest ==================\n\n")

principal = int(input("Enter the principal amount: "))

rate = int(input("Enter rate of interest: "))

time = int(input("Enter time in years: " ))

compound_interest(principal,rate,time)

opt = input("\nDo you want to try 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 script calculates compound interest based on the principal amount, interest rate, and time period provided by the user. It defines a function

**compound_interest** to perform the calculation and print the result.

Then, it prompts the user to input the principal amount, interest rate, and time period, calls the **compound_interest** function with these values, and displays the calculated compound interest. Finally, it asks the user if they want to try again or exit the program.
