Just curious: what did you expect? Sets have a different purpose,
basically to be able to do an 'in'

Firstly, these results may vary depending on operating system,
processor architecture and build options
Hi, Thanks for the quick response.
Being curious I actually expected something like this:
L={x:None for x in range(1)}
sys.getsizeof(L)
196660
That is why I wondered why 6 times is a lot given that a dict can do the
same at 3/4 of the mem-footprint.
Just got surprised about the overhead

Both sets and lists may be over-allocated. I expect that lists created with a
list comprehension may not be over-allocated, but if you

I hope it's clear that 3/4 here comes from 1/2 * 3/2. In other words
the dict table has 1/2 the number of entries, and
Following Oscar's comment, It's also O(n) vs. O(1) tradeoff.
