Python: Challenge task - looping through a list

Hi - The challenge task is the below

I need you to write a for loop that goes through each of the words in hellos and prints each word plus the word "World". So, for example, the first iteration would print "Hello World".

I understand why it's not giving what i want (the code i wrote is below), although i am not able to figure out what to do and the course is not letting me go beyond this, can someone help me please?

What i wrote is 

          hellos = [
    "Hello",
    "Tungjatjeta",
    "Grüßgott",
    "Вiтаю",
    "dobrý den",
    "hyvää päivää",
    "你好",
    "早上好"
]
for hello in hellos:
    str1 =  ''.join(hellos)
    print(str1 +' World')
    break

I think you may be overthinking it a little bit, the code can be done as:

hellos = [
    "Hello",
    "Tungjatjeta",
    "Grüßgott",
    "Вiтаю",
    "dobrý den",
    "hyvää päivää",
    "你好",
    "早上好"
]
for hello in hellos:
    print(hello + " World")

Your code is creating a single string of every value in the list. Then appending "World", then exiting the loop. It is never looping through again as 'break' cancels out of a loop when called.

The output which should be given is: "Hello World" "Tungjatjeta World" "Grubgott World" etc...

hello, I'm new to this and i was wondering why calling print(hello + " World")instead of print(hellos + " World") ? since variable hello has no value in it. i'm very confused right now please help.

hi Alexis, 'hello' is the variable being used in the FOR loop to loop through your list ('hellos), until the FOR loop ends your variable is temporarily stored in 'hello' , that'y why we are using hello instead of 'hellos'. I hope that helps.
