Develop module interest.py with functions calculate_simple_interest, calculate_present_value, and calculate_compound_interest. Each function asks the user for the input required for the formula and returns the calculated value.

s = p * r * t

s = simple interest

p = principal

r = rate

t = term of loan

P= F(1+r)n

P = present_value

F = future_value

rate = annual interest rate

years = number_of_years

A=P(1+rn)nt

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed
