"Hello World" For Loop Problem

Can anyone please tell me what is wrong with the loop I created? Thanks

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

for greeting in hellos:
    print(greeting + "World.")

The loop itself is fine, it's actually the print statement that is a bit problematic. When you concatenate two string using the + operator they are combined without any added spaces. That means that "Hello" + "World" for example would become "HelloWorld".

In order to get proper spacing you have to add a space manually. Like this for example:

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

Since there is now a space at the start of " World" the spacing of the combined string will be correct.
