Can I turn a generator object into a tuple without using “tuple()”? [duplicate]

This question already has an answer here:

It's possible to use the following code to create a list:

>>> [i+1 for i in(0,1,2)] [1, 2, 3]

Can a similar thing be done with tuples?

>>> (i+1 for i in(0,1,2)), (<generator object <genexpr> at 0x03A53CF0>,)

I would have expected (1, 2, 3) as the output.

(1, 2, 3)

I know you can do tuple(i+1 for i in(0,1,2)), but since you can do [i+1 for i in(0,1,2)], I would expect a similar thing to be possible with tuples.

tuple(i+1 for i in(0,1,2))

[i+1 for i in(0,1,2)]

No, there are no tuple comprehensions.

No; parentheses actually aren't the syntax for a tuple, it's the comma. There's no "tuple comprehension", see e.g. stackoverflow.com/q/16940293/3001761.

@jonrsharpe I know. >>> 1, outputs (1,). I would still expect there to be a way to do that though.

>>> 1,

(1,)

In python 3 you can unpack a generator using *.

Here is an example:

>>> *(i+1 for i in (1,2,3)), (2, 3, 4)
