I'm completely lost

How do I separate just the continents starting with A

continents.py 
continents = [
    'Asia',
    'South America',
    'North America',
    'Africa',
    'Europe',
    'Antarctica',
    'Australia',
]

for continent in continents:
    print("* {}".format(continent))

Hi Tapiwanashe

When I look at the challenge there's a hint -> HINT: Remember that you can access characters in a string by index Let's take the first element in the list 'continents' which is 'Asia'. 'Asia' has 4 characters: A, s, i & a. We can access these all by index. Here it is important to keep in mind that with indices we start counting from zero. So...

  • A -> index 0
  • s -> index 1
  • i -> index 2
  • a -> index 3

We can access these as follows:

  • A -> index 0 -> continent[0]
  • s -> index 1 -> continent[1]
  • i -> index 2 -> continent[2]
  • a -> index 3 -> -> continent[3]

We are asked to find all the continents which begin with the letter 'A' which means we need to check the first character so this is the character at index zero -> continent[0]

So...

for continent in continents:
    if continent[0] == 'A':
        print("* {}".format(continent))

Hope this helps!
