Python Python Basics (2015) Logic in Python Loop

Question down 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".

Error is Bummer! Didn't find all the hello's.

Any help appreciated

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

for hello in hellos:
    print (str(hellos) + " World")

I'm not sure if it's just a typo on your part, or maybe a misunderstanding regarding the workings of the for loop, but the item we'd like to concatenate with " World" is hello, not hellos (the whole list). The code for hello in hellos: ... basically means: for each item (to which we refer in each iteration by the name hello, but that's arbitrary, it could be item or anything else) in hellos, do the following: [the contents of the next line].

Moreover, converting the item to string is redundant in this case, since the list only contains string objects here. So inside the loop just write print(hello + " World").

That still doesn't work it gets another error and it doesn't even work in IDLE neither, the str( is needed 100%

There is also an unnecessary space between print and the braces (there shouldn't be). Now the could should work.
