Why doesn't Position work in this example?

Questions
1

Hi – I wonder if anyone call tell me why Position outputs { } (instead of {2}) in this example. Thank you in advance.

list = {1, 10}

pos = Nearest[list, 7]

Position[list, pos]

2

Because pos, which is equal to the list {10} is not in the list list.

Ah, I see. 10 is in the list but {10} is not. Is there a better way to fix it besides the following?

list = {{1}, {10}}

pos = Flatten[Nearest[list, 7]]

Flatten[Position[list, pos]]

4

If you only want the first element returned from Flatten then you can use

Position[list, First@pos]

Thank you!
