Question

write a function interest() that takes one input, a floating-point interest rate (e.g., 0.06, which corresponds to a 6% interest rate). your function should compute and return how long (in years) it will take for an investment to double in value. note: the number of years it takes for an investment to double does not depend on the value of the initial investment.

Answer 1

Code:

def interest():

   interest_rate = 0.06

   investment = input(int('Investment: '))

   yield = 0

   year = 0

   while (yield < investment):

       year += 1

       yield  = investment * interest_rate

   print (year)

NOTE: i wrote this code assuming that the investment for the next year is the same as the first year and so forth
