"Investment Calculator in Python"

Here's an example of a basic implementation of an investment calculator in Python:

This code defines a function future_value(principal, rate, years) which takes in three parameters, the principal amount, the annual interest rate, and the number of years for which the investment is made. It then calculates the future value of the investment using the formula future_value = principal * (1 + rate) ** years.

The main block of code then prompts the user to enter the principal amount, the annual interest rate, and the number of years. It converts the rate to decimal and calls the future_value() function with the inputs and assigns the result to a variable result. Finally, it prints the result to the screen.

You can customize this code by adding more features like compound interest, different investment options, etc.

To run this code, you will need to have a Python development environment. Some popular options include IDLE (which is included with the Python installation), PyCharm Community Edition, and Visual Studio Code with the Python extension.
