Python Introducing Lists Using Lists Continental

Having Trouble on "Iteration" Quiz on Learning Lists Coarse.

I am still new to Python, and I have no idea on how to target the first letter of each object in a list. Do I have it look for the "len" of each item and have it correspond to "first_letter"? Any help would be appreciated.

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

You have the right basic idea, but the index should be applied directly to the string variable :point_right: continent[0]

Also, the symbol for comparison is "==", just a single "=" is an assignment operator.

So should I have my code like this?:

first_letter = "A" for continent in continents: if len(continent[0] == first_letter): print("* " + continent)

This doesn't work, and I still don't know how to look at the first letter of each item in my list. Do I have to use the "len" differently or at all?

You won't need "len" at all for this challenge.
