Are list comprehensions syntactic sugar for `list(generator expression)` in Python 3?

Question

In Python 3, is a list comprehension simply syntactic sugar for a generator expression fed into the list function?

e.g. is the following code:

Answer 1

You can actually show that the two can have different outcomes to prove they are inherently different:

>>> list(next(iter([])) if x > 3 else x for x in range(10))
[0, 1, 2, 3]

>>> [next(iter([])) if x > 3 else x for x in range(10)]
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 1, in 
StopIteration

The expression inside the comprehension is not treated as a generator since the comprehension does not handle the StopIteration, whereas the list constructor does.
