Can someone please help me with the continental task?

In here there is a list of continents and i have to print only the ones that start with the letter A, how do I do that, I already tried to look on forums and in the past videos but it only shows a single string not in a list, the same code would recognize the first word of a list and not the first letter.

You can index a string (using brackets) to get a specific character from it, so to test if the first letter of a string stored in a variable named "word", you can do this:

    if word[0] == "A":
        # print here

And how do I index the first letter of a string in a list of more strings, because I only can get to index the first word in the list.

Using the loop that you wrote for task 1, where you pick out each name from the big list and print it. For task 2 you just need to add the test to limit which ones are printed.
