Hi Zhang,

The for loop is looking for continent in continents and we need to only print the continents that begin with the letter A.

I personally like to start with Pseudo Code:

// If continent starts with the letter A, print continent

For me, there are two things that we need to do:

  1. write an if statement and
  2. reference the first index in the array of continent making it equal to the letter A

When we look for the first letter in any array, we need to reference the first index like so: continent[0]

So in challenge 2, we simply need to add this condition:

    if continent[0] == 'A':

Our final code for this challenge looks like this:

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

I hope that helps!

Hi Zhang, you need to include a conditional statement in your for loop. The statement needs to check if the string starts with the letter 'A'. Read the hint carefully. Good luck!

Hi there,

It looks as though the task is testing the ability to pull the first character from a string rather than explicitly call out the index of the list of continents. Imagine you had 1000 items in your list, how would you find all the values that started with an 'A'?

The hint indicates that you can access a string character from the index. Since [0] would be the first character of the string, you can grab this value like this: continent[0]. From there, you can compare that value to the character of 'A'. Here's the code that I used:

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

Hope this helps :)
