hellos = [
    "Hello",
    "Tungjatjeta",
    "Grüßgott",
    "Вiтаю",
    "dobrý den",
    "hyvää päivää",

Hi, there

the problem is this part of your code

for word in hellos:
    print (hellos += "World")

you wrote a parameter called word, but you are not printing the parameter. Instead, you are print the list hellos.

The second issue that I notice is that the task wants you to print "hello world". When you write + "world" it will not include the space. It will print a string "helloworld".

Consequently, you want to add a string with a space like " world"

To sum up it should look more like this.

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

for i in hellos:
    print(i + " World")
