Python Introducing Lists Using Lists Continental

Checking if a list has strings that begin with a certain letter.

"I'd like you to now only print continents that begin with the letter "A"." That is the task, but how do I check this?
continents = [
    'South America',
    'North America',
# Your code here
for i in continents:
    print("* " + i)

You can access individual characters in a string by indexing, using brackets similar to working with a list. For example, since index numbers start at 0, the first character of "mystring" would be "mystring[0]".

You could then compare that to the letter "A" in a conditional expression as part of an "if" statement.

How would the code look like? I don't think I quite understand it yet...

In this case, in between the "for" and the "print", you might have something like this:

  if i[0] == "A":

Alright, I got it now! Thank you for your help.

His loop variable was "i", but yours is "continent". So you'll need to substitute the name in the "if" line to adapt it to your code.
