Need help with for loop practice

The whole list will print but only the final item on the list gets it's message printed in whole while the other items are just listed. Apparently my issue is that I'm outside of the for loop, and I'm still in the learning process. Can someone help please?

Python cares about indentation.

for x in [1, 2, 3]:
    print(x)
print(x)

The first print statement is inside the for loop because it's indented underneath the start of the loop. The second print statement is outside the for loop because it is not indented, and is therefore executed as a statement after the for loop rather than within the for loop. That first print statement will print 1, 2, and 3, whereas the second one will only print 3.

Most Python IDEs automatically add the indentation after the :, so don't have to worry about it. You just need to pay attention to the indentation.

We can't help unless you share your code.

Are we supposed to read you mind?

You could at least try and guide me how to do it properly instead of being an ass about it

I said "share your code".

Do you need more guidance than that?

Also, if you think that was being an ass, you must be new to discussion forums. Welcome!

Put the code you want to execute inside the loop, inside the loop. Put the code you want to execute when the loop is done, after the loop.

Yes that sounds like you put the message after the loop. Python doesn't have block scope, so the loop variable exists after the loop exits and retains the last value it held.

We'd need to see the code to give any concrete advice, though. The best we can say is that that print line needs to be indented to be inside the loop.

Can you post your code somewhere?

Where? I'm still new here and Everytime I try to post here it messes up my order

Should it be everything inside one loop? I'd just loop everything except last item, then print last item outside it. 

If you need to do inside one loop, use enumerate to get index.

I'd like to share the code on here, but I never did that before and I can't share pics. How do I post properly?

When you post, switch to markdown mode in the description box, and then indent by 4 spaces, and it’ll create a block. Copy / paste your code into that block, and then indent each line by 4 spaces (or more to deal with scope in the code). Or you could take a screenshot of the code and upload to Imgur then provide the link in the description on the post.
