Counted Loops In Python for this Scenerio

Question

Suppose there is an island with two rabbits (male and female). Every 30 days, the population of rabbits doubles. Write a program that has the user input the number of days and then calculate the new population. Use a counted loop.

Extension:

(a) Let the user specify the initial population of the island.

(b) Let the user specify how many days it takes for the population to double.

Answer 1

# Using Python:

def defaultPopulation(totalDays):

population = 2

for doubles in range( totalDays // 30 ):

population *= 2

return population

def populationWithInitial(initial, totalDays):

population = initial

for doubles in range( totalDays // 30 ):

population *= 2

return population

def populationWithDaysToDouble(daysToDouble, totalDays):

population = 2

for doubles in range( totalDays // daysToDouble ):

population *= 2

return population

# Run with extension b:

daysToDouble = 20

totalDays = 100

populationWithDaysToDouble(daysToDouble, totalDays)

Use 4 spaces for each indent instead of 2.

Also, these are functions, so you have to put values into them for them to give you output.
