how to write code to detect middle number in python array

Question

ex- a= {2,3,5}
mid=3

b={1,1,5,6,7}
mid=5

Answer 1

Is that an array or a `set`?

You know that the latter cannot have duplicate members. So if it was a `set`, <b> will have {1, 5, 6, 7} only

Should it return a single value even when the container has even number of elements? I was thinking, if <b> has {1, 5, 6, 7} there would be 2 middle numbers, 5 and 6 ...

What if the container only has 2 members in? e.g. [ 20, 23 ] or a single member like [ 2023 ] ?

Answer 2

Ｒｏｓｈａａｎ, good decision.
But I think that
middleNum = (len(array) - 1) // 2 = len(array) // 2

Answer 3

Damsara Welivita that is not an array I agree with Ipang
