Hi Greg, there are a few small issues with your code :)

1. Make sure to include the space between the hello and World by adding it to the front of str1.

2. Remove the while loop, it's not required in this case.

3. Make sure to use the value of hello (string item) for each iteration, not hellos (which is the list that you are iterating through.

str1 = " World"
for hello in hellos:
    print(hello + str1)

Hi Umesh,

Thank you for your detailed answer.

I did what you suggested and passed the test. I understand your reasons 1 & 2. I am not sure if I understand reason no 3.

Does the challenge ask me to print each word in the list + hello OR Hello world = to the number of words in hellos???.

I think that is what was confusing me!

Thanks!:)

The question wants you to print each word in the list + World. Below is what the output should look like:

Hello World
Tungjatjeta World
Grüßgott World
Вiтаю World
dobrý den World
hyvää päivää World
你好 World
早上好 World
