In this article, we will learn about the calculation of simple interest in Python 3.x. Or earlier.Simple interest is calculated by multiplying the daily interest rate by the principal amount by the number of days that elapse between the payments.Mathematically, Simple Interest = (P x T x R)/100 Where, P ...
