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
