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".

Not sure what I'm doing wrong here...

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

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

Try adding a space in the word "world":

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

Thanks Pepe, I figured it would be a slight oversight...

This catches me out quite often too. Often enough that now I always use interpolation with .format just to make sure my string is formatted soundly.
