I am getting the right output, and only added one line of code. I can't make it any better. What am I doing wrong?

continents.py 
continents = [
    'Asia',
    'South America',
    'North America',
    'Africa',
    'Europe',
    'Antarctica',
    'Australia',
]
# Your code here
for continent in continents:
    if continent[0] == "A":

Hi Darnell. You are really close! You have the correct continents but they ask for a bulleted list. Try using string concatenation to add a "* " in front of the continent in your print.

Thanks, Mark. I was running into the same issue and solved the coding challenge, but can you or someone explain why the [0] is required to pull each country starting with "A"? Thanks in advance.

Hi Christopher. You're welcome. continent[0] represents the first position (remember arrays start at index 0) in the string array. So the IF statement checks if the first letter is equal to 'A'

The first time through the FOR loop continent will equal 'Asia' and continent[0] will equal 'A' and continent[1] will equal 's' and so on. Hope this helps.
