How to check the status of hyper threading?

[ChenZhongPu]

Currently, the code to check whether the hyper threading is on:

if (total_cores * total_physical_cpus) * 2 == total_logical_cpus:
    hyperthreading = True

But it seems that the code above is not correct, because it can be partially on. For example, the results in my desktop:

❯ python3 check.py
  This system has 1 physical CPUs
  This system has 16 cores per physical CPU
  This system has 16 total cores
  This system has 24 logical CPUs

Why not compare tocal cores to logical CPUs directly?
