From Zelle chapter 8: Write a program that uses a while loop to determine how long it takes for an investment to double at a given interest rate. The input will be an annualized interest rate, and the output is the number of years it takes an investment to double. Note: the amount of the initial investment does not matter; you can use $1. Hint: Chapter 2 futval.py has code with a for-loop that computes the value of an investment...
