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".

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".

hellos = [
    "dobrý den",
    "hyvää päivää",
for words in hellos:
    print(hellos + " " + "World")

It might help to see the issue by reading the for loop. In this example, the loop will read:

For every words in the array hellos, print hellos plus the string "World".

When you read it like this, you can see that you shouldn't be printing hellos, but the word within the array.

Your loop should look like this:

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

hi jose, my code on this challenge doesn't work, i used the variable word but there's still a bummer saying they didn't find all the "hello"s, mind for helping ?, thanks

for words in hellos:#what does words have stored, and what does hellos have got
    print(hellos + " " + "World")#what are you trying to print here
#all seem good, except for 'hellos' in the print statement
#you are trying to concatenate, an array with a string

I was facing the same problem. I suggest removing the + " " + -- it's not needed. Add a space to " World" and it should be fine. Mine was.

print(word + " World")

This should be fine. Try it.
