Yes I'd agree with that. No more 'goto out'.

It's an interesting page:

Some days ago I suggested something different: maybe def can become a
function, then it can work as lambda (and still as the old def) too.

"GOTO" isn't even needed in QBasic (except for "ON ERROR GOTO
On Windows, I use WConio

It provides other screen functions you might have gotten used to in
QBasic as well.
On unix/cygwin, use curses.
I am not aware of any portable library though.
I used to use cls a lot in my QBasic days. Now I just don't.

You can only use the goto function if you use Python with line numbers,
thusly:

I'd say it's dispensible and not worth the added complexity.

No goto needed. If this makes no sense (which it may not if all you've
been exposed to is BASIC) it wouldn't be a bad idea to Google why you
should never use a goto statement.
To do a clear screen you'll need to use the method that your command
shell uses. The shortcut to this

BTW, I'm thinking to replace lines "time.sleep(3)"

How do I do that ?
Also I wanted to put at the end something like

There isn't one.
One defines functions and calls them. One uses for and while
loops. One uses list comprehensions.

it's more descriptive than anything. It's any language change that's designed to
