This is a list comprehension, resulting in a list as its result.

This is not a tuple comprehension - Python does not have one.
Instead, it is a generator expression:
x for x in range(10)
inside some brackets, which are just group as you might find in an
expression like:
(3 + 4) * 7
If you want a tuple, you need to write:
X = tuple( x for x in range(10) )
which makes a tuple from an iterable (such as a list, but anything
iterable will do). Here the iterable is the generator expression:
x for x in range(10)
