Hi Seymore!

Happy to see that you are moving on from
"reading much; understanding nothing; thrashing"

to

"reading a bit; understanding a bit"
[And thanks to Denis to getting you out of your confusion-hole]

So heres a small additional question set that I promise will more than repay
you your time.

Better done in python 2. But if you use python3, below replace
range(10)
with
list(range(10))

So now in the python console, please try

a.
>>> range(10)

and 

b.
>>> print (range(10))

And then post back (without consulting google!!)¹

1. Are they same or different?

2. If same, how come different expressions are same?

3. If different whats the difference?

4. [Most important]: When would you prefer which?

=================
¹ Actually its ok to consult google AFTER you try
