To loop through a list you can use: 

for index_variable in your_list:

to print the variable in a formatted way use:

print("{} World".format(your_variable))

where {} is replaced by the formatted version of your_variable. Putting it all together you get:

for greeting in hellos:
    print("{} World".format(greeting))

Your for-loop is a bit of, its syntax should look like this : 

something = ["stuff1", "stuff2", "stuff3"]

for all_stuff in something:
    print(all_stuff)

# Output : 
    "stuff1"
    "stuff2" 
    "stuff3"

In this challenge you are supposed to print out the word "hello" in different languages from a list, followed by the string "world".

I'll try to explain : 

hellos = [ "Hello", "Tungjatjeta", "Grüßgott", "Вiтаю", "dobrý den", "hyvää päivää", "你好", "早上好" ]

# First we must set up a for-loop to reach the items inside the [hellos] - list. Like so : 

for item in hellos:

# The word "item" can potentially be whatever you wan't, it's just a placeholder-name for the items inside a iterable. 
# the "hellos" basically just tells us which list or iterable we are going to reach inside of. 

# Now we must set up the code to print out the wanted string, which is "item + world." 
# we can use [format] to put out items inside of a string, with the use of another placeholder "{}".

print("{} world!".format(item))

# which puts the current item where the "{}" is placed. You see ? 

# your complete code should be something like this :

for hello in hellos: 
    print("{} world!".format(hello))

I hope this made it a little bit clearer. English is not my main language so I might explain myself poorly sometimes.

Hope it helped. Good luck.

So this script is looking to print "Hello world" using all the different hellos in different languages.

So I would set up a loop for all the hellos in that list.

something like

hellos = [ "Hello", "Tungjatjeta", "Grüßgott", "Вiтаю", "dobrý den", "hyvää päivää", "你好", "早上好" ]

for hello in hellos:
  print("{} World!".format(hello))

So think of the 

for hello in hellos:

As saying: Hey python, for each hello in my hellos list, do this.

then you just have the format syntax, which follows the "{} Test".format(whatyouwant) syntax
