Why is there no tuple comprehension in Python?

StackOverflow

As we all know, there"s list comprehension, like

[i for i in [1, 2, 3, 4]]

and there is dictionary comprehension, like

{i:j for i, j in {1: "a", 2: "b"}.items()}

but

(i for i in (1, 2, 3))

will end up in a generator, not a tuple comprehension. Why is that?

My guess is that a tuple is immutable, but this does not seem to be the answer.

You can use a generator expression:

tuple(i for i in (1, 2, 3))

but parentheses were already taken for … generator expressions.

Since Python 3.5, you can also use splat * unpacking syntax to unpack a generator expresion:

*(x for x in range(10)),
