12.1 More mapping

The map() method calls a function for each value in a list and then outputs a new list with the modified values.

def increment_by_one(number):
    return number + 1

my_list = [1, 2, 3, 4]
result = map(increment_by_one, my_list)  # returns [2, 3, 4, 5]

📝 Instructions:

1. Create a function named multiply_by_three that will multiply each number by 3.

2. Use the list map() function to run the multiply_by_three function through each value in the list.

3. Store the new list in a variable named new_list and print() the new values.

💡 Hints:

• The map() function will apply the specified function to every item in your list.

• Remember to store your result in the new_list.
