for words in hellos: print(hellos + 'World') Bummer! can only concatenate list (not "str") to list

Why does it say that?
hellos = [
    "dobrý den",
    "hyvää päivää",

for words in hellos:
    print(hellos + 'World')

The error is being raised because you're trying to concatenate the list hellos with the string "World". Instead of printing hellos + " World" you need to print words + " World". When you use a for loop, the first name you give it (example: 'x' in for x in y) represents each item in the iterable you give it, which is the second object that comes after the 'in'. Also, make sure you include an extra space at the start of your string! You want it to print "Hello World" not "HelloWorld".

for words in hellos: ti = words + " World" print(ti)
