Python Introducing Lists Using Lists Continental

Asia not being found in list in Treehouse editor, but I can print the list just fine on my machine running 3.6.5.

Here is my code in both Treehouse and my machine:

continents = ['Asia', 'South America', 'North America', 'Africa', 'Europe', 'Antarctica', 'Australia']
for continent in continents[0:6]:
    print("*" + continent)

When I run the program in cmd prompt, I get the full list from Asia through Australia. However, when I run the code in the editor it tells me Asia isnt being printed and errors out.

I added the [0:6] just to make sure I am getting all of the list items, if I run the program w/o the [0:6] on my machine the whole list is printed out too.

What am I doing wrong?

I would expect a slice of [0:6] would cut off the last item, "Australia". Doesn't it do that for you?

But when you get the message "AssertionError: '* Asia' not found...", what it is actually pointing out is not that the name "Asia" is missing, but the space between the asterisk and name is missing.

Add the space, and drop the slice (or extend it to [0:7]) and you should pass task 1.

Hm, interesting. Didn't think to try that, now it works.

When I run it on my machine with the slice [0:6] it prints out all 7, which is weird. Then if I change it from 6 to 7, it also works. I'll take a look into that.
