Python Introducing Lists Using Lists Continental

Print continents starting with A

I don't understand why this isn't working. For each item in the list continents, if the 0th character is A, print the item.

Edit: the index needs to be in square brackets for some reason, but I don't understand why this works. It's not a list.

continents = [
    'South America',
    'North America',
# Your code here
for item in continents: 
    if item(0) == "A":
        print("* " + item)

You sort of answered the question already: "the index needs to be in square brackets".

At the moment you are using parenthesis instead of square brackets, hence the error.

I figured that out, but I don't understand why it's the answer.

A string is an iterable data type, you can traverse it, eg:

for character in 'foobar':

In most languages it's just an array (list) of characters "stringed" together and as such you can access it by index.
