I asked you to try
list(range(10))

Did you try EXACTLY (cut-paste) that?

You are claiming to have tried
list(range(10)

Thats one closing parenthesis less

The interaction with your version would go something like this:
[Two versions 
The KeyboardInterrupt comes from giving a control-C
Dunno what happens in codeskulptor
]

>>> list(range(10)
... 
... 
... 
... )
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> list(range(10)
... 
KeyboardInterrupt

1. You are reading too much
2. Trying tooooo hard

Think of riding a bicycle.
Cant do it by reading many books on cycling -- thats 1.
Nor by holding the handle so hard you tremble -- thats 2.

Just relax a bit...
And take small steps

Chill... as Chris joked, no monster in the computer (or on this list!)

It loads?? As in 'load-up-a-van'??

When you see:

>>> 10
10

1. Does someone (a clerk maybe) in the computer count to 10?
2. Or do you, seeing that interaction, count to 10?
   [If you do, replace the 10 by 1000]
3. Or do you, remember what it means to count to 10 without having to do it?

Now go back to your statement about 'loading' and find a better verb
