# Exercise
# In this exercise, you will need to add numbers and strings to the correct lists using the "append" list method. You must add the numbers 1,2, and 3 to the "numbers" list, and the words 'hello' and 'world' to the strings variable.
# You will also have to fill in the variable second_name with the second name in the names list, using the brackets operator []. Note that the index is zero-based, so if you want to access the second item in the list, its index will be 1.

# write your code here
second_name = names[1]

strings.append("world")
# this code should write out the filled arrays and the second name in the names list (Eric).

print(strings)
