I can't solve the second part of the challenge when it is asking to print the continents with the initial "A" . Can anybody please help? Thank you!

continents.py 
continents = [
    'Asia',
    'South America',
    'North America',
    'Africa',
    'Europe',
    'Antarctica',
    'Australia',
]
# Your code here
for  continent in continents:
    print("* " + continent)

You need to add an "if" statement to control when the "print" is done. Give it a conditional expression comparing the first character of "continent" to the letter "A".

You can isolate a character in a string using an index (value in brackets).

It's impossible to check the indentation without Markdown formatting (as I used below), but if your indentation is already correct it looks like you're only missing the colon at the end of the "if" line:

for continent in continents:
    if continent[0] == "A":      # <-- colon added
        print("* " + continent)

So sorry Steven I'm sure your answer is very clear but i can't figure out the solution.

Try adding an "if" statement using the hints given. If you still have trouble, show the new version.

I'm confused on why this works.. in the if statement you put ( if continent[0] == "A": ) so wouldn't the computer only check and print the location of continent[0] which is Asia instead of printing out the other continents? I hope this made sense.

So Steven I've been trying lots of things maybe the less embarrassing version i wrote is: for continent in continents : if continent[0] == "A" print("* " + continent) And obviously is wrong.
